292 TURBO-WHAT COMES NEXT? 

1. Put the 2 bbl on a good intake manifold with headers and everything else stock to show how much power just the intake manifold cost. 2. Connect the points distributor to the white wire on the MSD box so show how much good ignition is worth. 3. Bowl port the head and put in a street friendly cam to show what a 'comprehensive' build will do. Don't worry about porting the head yourself. Many guys working with these are going to be home porters anyhow. 4. Swap the 2 bbl for the 4 bbl to show how the modified engine responds to more airflow. 5. Boosted runs with a proper turbo. Put heavy springs in the distributor if you want to slow the advance. Personally I'd lock the distributor advance, connect the MSD tach output to the Holley EFI, run the Holley computer in batch fire and have it handle the advance. You can switch to a 4 bbl throttle body then too if you like. Port EFI is a bad idea on a siamese-port engine. Plot out the firing order and you'll see that you don't have even intervals between draws on an intake port. EFI will have worse fuel distribution. So bad it will barely run fuel distribution.

A lot of us have been waiting for a video like this for years. We have watched videos on performance mods on small blocks, big blocks and ls engines until there coming out of our ears. I have a 62 chev sitting in the barn that I would like to drag out and mod someday and I would like to use the 292 that's in it. The more variants you can produce on 292 mods the better. Keep up the great work.

I say start stock-ish, then add upgrades. More data... More videos!! Let's see what this 292 can do!!

I dig that you ran it basically 100% stock, I dont think Ive ever seen any motor ever ran with a homemade turbo kit with a points distributor.

Would be awesome to see you work on a ford 300

Man, your enthusiasm is contagious! 👍 The answer is, Yes, test it all!

Please do a Ford 300 6 next!!!

Thanks for doing what you do for us, very informative and interesting

Honestly I have a 250 Chevy mild cam bored .40 over. And id LOVE to put some power added but NOBODY showed any concrete info! I can’t thank you enough for including us other guys!

Remember People, the connecting rods in a 292 are weak and the engine has a long stroke, so a rod upgrade needs to be done soon. Summit sell a nice cheap set of H-Beams for 300 bucks (a very quick search). I'm less concerned with the pistons. I would love to see this old girl breaking 500 HP than seeing it blow up short of that.

Thank You Mr Holdener!!!!! Some of you Inliners send/loan this man some cool stuff to test!!!!!!

This is an awesome series, thanks for all the effort you put in it! The bore spacing on these 6 cylinder engines is 4.4”, just like a sbc, (or as LS) if I recall. There were some efforts to creat a cylinder head by sawing V8 heads and furnace brazing them together once upon a time. I’m wondering if anyone has a modern head design with good combustion chambers and good individual ports. Those long rods and heavy pistons are likely to hold rpm down no matter what you find, but I’m looking forward to what you can show us. Let’s see more than the PowerNation build!

Love the channel. Had a 69 Chev 1/2 ton years ago with a 250 6 cyl that I had rebuilt. Was amazingly quick and never left me stranded. Also was three on the tree that I learned to speed shift 1st to 2nd. You brought back a lot of fond memories.

I got an offy and a 390 holley, let me know, I'll drop it by.

Love what you are doing with this channel. You are answering questions that nobody else has. Keep it going. I'm savoring the upcoming Buick 455

It wont be easy to create port injection. They don't fire evenly. #1 fires, #2 fires 480 degrees later, and #1 repeats again only 240 degrees later. With that big siamese intake hole, #1 will be very lean, #2 very rich. You will have the same problem with 5 and 6. I think blow through is your answer unless you want to create a port divider.

So far this has been one of my favorites

Great job!! You have validated my choice of replacing my straight 8 in my 47 Buick with a 292.. I have added an m90 eaton on a custom built intake on mine to help overcome the limitations of the stock head, a boost referenced Holley and a modified hei distributor.,I have built for torque to haul my heavy Buick and vintage caravan. Thanks for thinking about us other guys and I will be following the build.,.. Richard you are the man!!

Thanks for the no sleep. And yes to more turbo testing

Richard, would really like to see the intake on the stock long block. Also intake plus cam and springs on a stock head would be killer too. Thanks, loving this 292!

I’m so pumped on these 292 tests I’ve built a 292 194 ported head cam Langdon exhaust manifold and offy intake and the the thing moved a 5000 pound 1 ton with 4.56 gears pretty good must have been at least 250hp but the torque was crazy sadly it melted the stock cast pistons but the head was still good

Richard, I'd watch a 45 min video of yours. The info you put out is very interesting. I think, test the bolt-on mods on the stock longblock (intake w/ header, intake w/manifold, intake w/boost). Then the same tests after cam, lump port head, and better rods (for the big boost!).

Maybe you can find someone who has a Brazilian EFI intake like they run on the Opala. They do crazy things with those engines

I like seeing the best cheap/free mods for power for any engine. I never have enough money to do anything too big. I have to do small, cheap changes s little at a time.

I remember in the 70’s Hot Rod did an article on the Chevy 6s and in the article they made dividers for the intake side of the head. Perhaps someone at Hot Rod could dig that up for you. I would think that would help with fuel injection....

I love the other guys videos it would be cool if you did a jeep 4.0 i6 and a chevy 4.2 i6 and a ford i6!

Start with NA aftermarket 4bbl Clifford intake and exhaust - add a bump stick and then a smaller turbo. this is fun just watching!

See what you can get out of it NA! Cam, porting, 4bbl manifold, headers and forged pistons, rods and crank if that’s a thing haha. Then turba!!

Would love to see a Sprint 6 with all this work done to it! This is such a rad channel! Glad to see your subscribers up 83k! Congrats Richard!

A few ideas for testing. 1. Crank scraper and windage tray test? 2. Maybe pull vacuum on the crankcase? 3. Oversized valves and unshrouding the chamber. 4. Propane VS pump gas while under boost. 5. Water methanol injection.

I'd love to see how much you can get from a 300 six..

As a teen I drove a 67 Chevy Nova, with the 230 ci, 6 cyl. My fathers friend gave me his keys to run an errand. It was rated a 140 hp. I was so surprised at how peppy and fun it was to drive. Almost instant throttle response due to hp to weight ratio. Great little car and engine. That was with an auto trans too. I’d buy one now, if I could find a good one.

Knowing cylinder distribution would be awesome, and a great way to pick up safe power. Not saying anything you don't know. I will say though, you are doing this for the fans and the guys who have these in their cars. Almost no one will mod for distribution. Unless you are going to make a manifold to sell, just testing what makes power is all that's necessary. Would be good info to know if one intake distributes better than another, but, most won't care. I'd like 4 set-ups: 1. Bolt on NA 2. Bolt on Boost 3. Built bottom end for high RPM NA 4. Boost the built bottom, massive low RPM torque and a good average power and RPM range. How you find these "Recipes" is really fun to watch. Seeing this on a 300 Ford too! Miss mine.

Love your vids! I would love to see tests of the manifold on stock and ported heads before cam change but that may not really show anything. As far as injection I would just go with throttle body injection. Or maybe run the injectors upstream on the runners for each pair of cylinders. Maybe about 8 inches from the valves. Go with full control of the ignition. It'll kill the engine before mixture issues. keep testing.

My two cents... Test out every scenario you can come up with just the way you were describing it at the end of this video. Show is many stages of what you were doing so we can see what difference those modifications make. I really like the idea of this other guys series.

Start where most people would. Cam upgrade, and different intakes. Then go crazy. This is great watching.

It would be awesome to do the top end parts: head, cam, intake manifold. Then same under boost! Then add fuel injection (sniper efi or multi-port) and more boost! The long videos are cool Richard, I promise we’ll watch the whole thing!

Loving the 6 cyl!

I like all the sbc, sbf, and LS stuff but this is the type of thing I really enjoy seeing bc it's different. I would actually like to see you do an in-depth porting job on the stock head and give some pointers. I'd think porting basics would have to carry over to more common engine combos

I don’t have one of these but love to see the videos. Excited for the 500ci

Love to see an actual street build - 91 octane, good idle and an rpm range that isn't silly high, and maybe even some MPG potential - most guys running 6's aren't looking for stupid high TQ/HP numbers

Richard, Progression Ignition makes a super HEI style distributer, No centrifugal advance weights, & fully programable/adjustable via cellphone/Bluetooth, built-in 2.5 Bar boost reference MAP sensor. It's the answer to your timing concers, made for carb turbo applications. See their YT & other demo videos. You will love it!

Not to spend your money extravagantly, but I'd like to see a set of rods of pistons installed and big boost added with your EFI manifold . Can you make 800HP? What an incredible project this is for 2020. Never get tired of listening to you Richard.

Would love more retro builds, I'll click quick and hard on any straight 6 or FE block engines, multiple carbs go to the front of the line. Great content! Thanks

Build creep, I love it!! Just shows Richard is one of us. Love to hear your "reasons" for needing EFI, Engine management, etc. We have all been there.

Give that poor old motor a bath, asap! Looking forward to seeing you fab an efi inlet for it.

Love the 'all stock' idea with homemade intake and two stock carbs...the result would be good eye candy and a couple weekend of effort.

Thanks for all the help. You save us alot of time and money. I have a 64 chevy c60 tilt cab that has a 292. I also have a few small block Chevys, vortec and fast burn heads and a 500 Cadillac. You tests will help me make a decision on witch way to go. Thanks

I have truly loved this particular project. I've been eagerly awaiting every single video release! Can't say that about your other projects. You're awesome Richard. Not uppity and a good down-home greasy fingered fella.

Run all the mods together , I’m finding this way more interesting than the v8 stuff as I’ve seen lots of that so thanks for that Richard

I'm Brazilian American and these are hot in Brazil I have a uncle that welded and cut two SBC heads to make a cross flow head. I know he didn't come up with it but I would love to see this with itbs like an rb but bigger and old schooler haha. And I would love to see lumps in the heads and maybe some Weber's.

Richard I would use the head you have and just give it a basic clean on the ports remove casting bowl blend , do a nice valve job, mild pump stick, I wouldn’t go all out crazy as the majority of folk wouldn’t go all out crazy on a six. Some nice boost 7-10 max with out sacrificing reliability forget about spraying it just a good driver with good power. Thank god it’s not another LS series... Great work keep it up.

Make as many videos about this engine as you can.

Go crazy love the content keep on keeping on 💯🇺🇸🏁👍👍

Richard, Power Nation did a similar build and test not long ago, just short of 400 hp, if I remember right. They're concern was bottom end pistons, etc, holding up to take additional boost. With a refresh and mild boost we know the 292 should make shy of 400 hp. Go ahead and rebuild with forged pistons, rod bolts, studs, springs, intake w/2or 4bbl, etc, so that you can push it and it will live.

I think your definitely on the right path! Test it all, would be great to see what can be done with a few more upgrades in the name of durability.

I would really like to see a draw-through turbo set up. To really be one of the other guys ,its what you need. Everyone does blow through. I love the stuff you do!!!

really enjoyed all the test richard on the 292, here in australia we have a GM holden 186 and 202 cubic inch engines, based on this 292 family engine, so really enjoyed what you have done on the dyno , please google holden 202 and you will see the australian made little brother of the 292 , cheers mate

I'd love to see this thing come to fruition in stages. The way you're already going about testing this little dude is awesome. I enjoy seeing all the things, especially stock parts with boost. Definitely recommend 6 port mpfi and some electronic ignition so uncle Rodney doesn't window the block. Keep it up bro!!!!

Oh man I’d love to see a gt35 turbo too! That’s exactly what I was considering for my 300

Just how you laid it out is perfect!!!! Can’t wait to see the increases in stages!!!!👍🏻

Intake comparison on modified engines. To really show any separation/differences between the intakes.

One improvement that would be helpful for guys running stock/slightly modified 194, 230, 250, or 292 sixes is the exhaust manifold from the heavy truck 292's. It has a 2.5" outlet and a better design for flow. These manifolds are still available because this engine is still in use in farming, especially combines. The last one I bought was for a Massey Ferguson.

My two cents and a few more, don’t worry about the length of video, I like more details. Timing, a/f and stuff like that. I’d do A intake test on stock just to show if it’s worth spending the money if you’re not going to do anything else. I’d like to see twin 35’s off a split header. Definitely interested in knowing the rod length in those. Keep up the great work

It would be interesting to hog out that intake manifold hole, gasket, and adapter to the max as one of the intakes tested to see the difference on spool and power

Love your passion,keep it up!

An NA with side draft carbs might be interesting. I do also like to see a full work up of other guys inlines. Maybe some flathead styles, maybe an inline 8 cylinder?

3:45 I'd think trying different intakes and induction setups on a stock engine would be the better route for testing,imo. I'd think most guys would be working on a stock engine , and would like to know if the bolt on stuff is gonna be worth it , or do they have to go for boost?

Your Aussie intake manifold will give you equal fuel distribution. Hundreds of of hours were spent on that intake's design. Your lump port head is a must, you'll pick up a ton of flow. If you want to do port injection then you'll want to see if you can borrow a head that's built from 2 SBC heads, that's when you'll get into your crazy power numbers. We won't get tired of this 292 stuff so don't be concerned about how long your videos are. Before you pound on the 292 anymore, check on the rod bearings. The piston n rod assembly is heavy and the bore to stroke ratio isn't the best. Looking forward to the next video, thank you again sir

You're the man Richard....keep up the great work

You have some great ideas. Port injection and timing control is the way to go. Size the turbo and make this the stump puller it was meant to be. A ported head would be interesting it see how much more you can squeeze out of this.

I seen a guy over at Little-River Dragway that ran a turbo inline 6. I would love to see you go wild with this one!

Awesome Richard, just do what you think, loving it 👍

Do the mods in a the order most people would do them. Intake manifold shootout first with headers. Then cam. Then headwork. Then everything else.

You could run tighter advance springs to bring total timing in later. Build a sheet metal intake with wide pattern injectors and an msd ignition so you can tune the timing table. I think this would be a cool project to have a shop that has a rotler cnc do the dimple port on also. Veicomer has been making big power with dimple porting for years.

I know it’s a lot to ask, but a intake test stock and modified would be awesome! I’d also love to see a open vs dual plane and maybe even a multi carb setup! But blow through multiple carbs would be a nightmare to setup

If you’re able to I’d love to see the intake and header test both modified and stock.

That plan sounds perfect, especially the efi part. im excited 😀

Modify to your liking then see what it can max out at. Really like the i6 stuff.

Seriously great job Richard , love this series on the 6 banger already & am really impressed by the creative mods so far . I personally would try simply matching & porting the std manifolds & a good head port first because it would be the first stage most guys would try with boost before spending big bucks on go faster goodies , then go onto cams , better manifolds , heads & bottom end etc .

Baffle the floor of the intake just below the carburetor. You will need to either place temp or Air/Fuel probe at each exhaust port with headers. You will need to test different baffles until you get even distribution. Test stock to see which cylinder needs more fuel. The baffle can be screwed down for quick change. Love your videos. Thanks for what you do.

EFI!!! I love your idea with that! I agree entirely! Distribution can really be an issue on the long 6. But with that solved the sky is the limit. I love inline 6 builds for the torque they provide as well as the long dependable lifespan they carry. But they are often overlooked. Thank you so much for building one and doing so in such a thorough manner! I say EFI long runner intake 2 injectors per runner placed early in the runner and take it from there. Can’t wait to see the development!

3 deuces would solve the fuel distribution, but I wouldnt wanna be the guy building the charge tubes!

Can't wait for the rest of this series, PLEASE do a 225 slant 6 next. I have one in a 1962 speed boat, it's had a full rebuild with a 500 Holley and Cam. I'd love to throw a turbo at it. Love your work. Matt.

I worked with 250s and 292 my whole life. Good to see you working on the straight 6. I have a lot of stuff for these engines in Brazil.

I'd would be interested in seeing the aftermarket intake with the two barrel, headers, RV cam, and stock ignition. I would also like to see the header fitted with individual wideband O2 sensors for each cylinder to see how bad the mixture distribution is initially and then after you create your fuel injection intake.

Intake manifold shootout stock and then modified.

I don't know about anyone else but I currently sit through an hour video watching

I would so watch 30 minute long videos.

If you start out with the cheapest and/or most obvious upgrades and go up from there in steps. That's how I have to do it. I've got a family to take care of.

I think it would be interesting to get as much H.P./Torque from the factory parts ie ported and shaved heads maybe a n RV cam, ported stock intake etc. then start adding pistons, roller lifters, Offy intake, then turbo/N2O. Either way, you won't go wrong and we'll love it.

Timing advance was always tuned by changing springs on the centrifugal advance. Points gap should also be set using feeler gauge, points cam also has duration, on bikes changing this and using better coils could produce significant power.

YEs multiple Intake shootouts. this is going to get so awesome so fast. One Snail of an engine + one Snail = FUN.

Love the other guys series! I’d love to see other inline sixes like a Ford 300, Mopar 225 (or even better a short stroke 170, but good luck finding one), and AMC 258 (or 4.0 or 4.0 stroked to 4.7). Or how about an International 345 v8 out of a Loadstar 1700 school bus... gotta be about half a million rusting away somewhere out there!

It will be cool to see compound turbos on it

Intakes in stock and mod!!!

I'll bet you'd be surprised how many of us would watch an extended video.

I always heard the older guys talking about the old slammin straight6 's drag racing in deuces or Camaro and they say you gotta get an intake and go full roller and balancing tryn to get some rpms. But then they can pull the wheels! Several guys say worked over Camaros w 250s gone into 12s. I'm over 40 so that impresses me...

You are pretty great with your logical explanations of why you want to do what. I am always right there with you. If I had one of these the first (or maybe second, after exhaust) thing I would want to do is change the intake and install a 4-barrel. I would want to know how much power that would get me. After that I would want to put on a better head. I already have the better intake so no sense going back to test the new head with the stock intake. I would want to know how much more power the head would get me after I already have improved intake and exhaust. Keep up the good work!

Intake, stock bottom end and exhaust manifold, then intake, stock bottom end and headers, then heads and cam and EFI.
