GM Inline 6 Intake Blocks Explained EP.10 

This is a massive improvement over the factory clamps! I worked on the big brown delivery trucks with 292’s and 300’s and for 16 years until they were phased out, this was a huge problem.

Thank you for making the video and doing a great explaining your improvements to its factory flaw . Thank you ! I'm in the rebuild of my stright 6 as well

My first car was a 64C10. It had a 230. I put on an Offenhauser four barrel intake with an adapter for a Holley 500cfm two barrel. Hooker headers and had my cam reground. 375 hp 396 grind. 500 lift and 290 duration. Pretty fast for a 6. The intake came from my friends Dads oval track race car. It was fun. I won races with it.

Your dog has their own parking spot. I like that :)

Excellent work!

Wow. That is awsome brother. Looks great!!!.

I like the fuel injection system ! With a carb 1-2 and 5-6 will always run lean compared to 3-4 with those intakes ! I put together a 250 back in the 90's had ten grand in the motor to avoid the lean issue I had a sheet metal intake made to staighten out the intake runners ,for performance the inline has to be in a very light car as they just don't have enough torque to pull a vehicle more than 3000lbs with the driver ! I put a 230 crank in it, as it's 30lbs lighter than the 250 , I traded 20 cubes for 30lbs less rotating mass , also installed 11to 1 TRW piston for a 238 that worked out to be right at 14to1 with the combination chambers in the head . ( $8 a gal fuel only ) plus the cam was .710 lift solid roller, and most of the money went into the head, not to mention the valve cover to cover the valve train , custom $400 of 1990 money! Had to Rev it to about 8000 rpm to get anything out of it ! It had nothing under 4000 rpm Finally I replaced it with a 7:1 427 big block set up for a 8-71 . Sold the 6cyl to some kid that had a 65 chevy II for $500 best sale I ever made ! Should of had a V-8 ! Have fun people .........

nicely done

I agree with you on the idea of having something different I have a 292 l6 in my 65 C10 my son keeps telling me to LS swap it . Every truck has an LS or a 350 in it , it’s hard to find a l6 at the truck shows I attend I think your on the right path and will probably have a unique set up and crowds will be gathered around your truck 👍🏽

Amazing!

You could make that longer and make a long tub intake. Like a 4 inch spacer between the head and intake.

Super cool!

Very good redesign and improvement. Thier is also a another use for this type design. The jeep inline 6. The 4.2 and 4.0 would benefit from this.

Very cool

Clean

You need to see about making those for Gm,Ford ans Chrysler. There is a small market for the inlines and getting more popular every day. I have been thinking about building a Ford 300. Just because I want to be different from everyone swapping Ls engines in everything. Thank you for the content.

brilliant!

I like your vids Bro.. should I use Summit or can you recommend a site to get my 292 aftermarket parts from . I just need to look through your vids, I'm sure it's in there somewhere ✌️

I'm interested as well. Do they have to be welded or can you add a gasket and clamp the intake flange to the adaptor flange using the stud? Any thoughts on creating a wedge shaped center insert to extend just slightly between the injectors which may isolate the injectors and would create better airflow around the bolt boss vs cutting or shaping the boss. I have not seen your prior videos so I don't know if this issue has been brought up.

Great idea, do you think these would work with the Langdon style cast iron headers? I’m running a 292 with Clifford and Langdon. Every time I take it apart it seems like I have an exhaust leak.

Thank you for the "no frills" video. I'm so tired of loud music, silly hosts and the like. You just say what needs to be said.

Hey buddy I know this video has been on since April but I got a question for you where could I get those blocks at for the intake because I'm not going to run fuel injection is there any particular place to get those can you help me out

So, I've built a few of these engines with upgraded manifolds (mostly for eliminating the "integral head"). Other than the mounting improvements, is there any performance improvements with them? Maybe I should check out your website..

Does the direct injection make a big difference? the old two-barrel carbs weren't too bad on mileage in the first place and if it had an agriculture cam grind a tank would last a month of Sundays,

very nice adapter kit . but i question why you did not ceramic coat the headers too, plus that intake manifold is going to require 2 support bars to the engine block , now that you have added much more weight to the intake manifold ,it is going to need weight support

excelent idea!!! where could I buy these intake blocks? I didn't found it in Ebay or Amazon... thanks!!!!

I have been throwing the idea around to build an inline 6 chevy and would like to use fuel injection. Which system are you using and where can it be ordered.

What benefit other than the injector boss, do these have? I see the Aussie Speed manifold has the boss for injectors?

Are they a form of Lump Porting? Will they work with a 500 CFM type AFB Four Barrel Carburetor?

What's the reason for the blocks? Looks like it would be easier and more cost effective to just machine the Aussie Speed intake for the injectors. Since they already have a pad on each runner just for that.

Do you have an estimate on what the purchase cost would be?

Are they aluminum so they can be welded to an aluminum intake?

No galling issues with titanium fasteners? Special coatings?

I would love to get my intake blocked… it’s a real pain setting up! I would definitely support getting these blocks fabricated

Are you going to make those to be sold?

i can see one possible downside to the use of just one bolt, even though, i do like it. if the stud comes loose in the head, when you take of the intake, you have to also take off the exhaust header.

I used a remflex gasket on my inline 6 and have no leaks

You didn’t port your cylinder head?

Where do I buy these?

Why wouldn't you just modify the intake manifold? That one you have seems to have the bosses for it.

Does anybody have a stovebolt conversion like this?

Caterpillar C15 exhaust studs

I am interested, very interested.

3/8" not 3/16"

Way to think out of the box, instead of bitching and complaining like the rest of the GM guys do.

Shame what Larry's done to Clifford.

SBCs are a dime a dozen, why would you even think about a inline 6?

Awesome work! Im not easily impressed!
