We'll continue to post these episodes here on RU-vid. If you can't wait for the rest of the build, visit our site to binge-watch: www.powernationtv.com/shows/musclecar
I don't know how "Old School" you guy really are but you should know that you need to set your dwell before you finalize your timing. Feeler gauges only get you close.
@@v8sserieschevy917 Yeah. As I recall, a lot of older muscle cars had a power valve that would blow out if the engine popped back thru the carb. The remedy was installing a check valve on the bottom of the carb - where I just can't remember, it's been 50 years for me.
@@robj2704 we just ran a lot of quadrajet. The newer Holly's may not have that issue. I have very limited experience with them. But nothing sounded as good as a qjet opening up.
@@v8sserieschevy917 Yeah. I remember back in the day (late 60's), could get a mechanical secondary mechanism for the qjet and bypass the vacuum feature. Actually, it didn't work all that good since it would dump the butterflies open without shooting additional fuel in and the result was a bog of the engine followed by a sudden jerk as the engine caught up. This put a real strain on the motor mounts - and would break them (ask me how I know...lol).
Tuning an old carbureted engine with points and rotor to it's sweet spot is a dying art form. You guys keep it going! Love to see people of my generation and younger (I'm 42) who know how to do this properly. Mechanics at your local dealer who have only been trained on modern cars wouldn't know where to start.
I had a 73 mint Camaro.Bronze brown metalflake exterior..Biege cream vinyl top. Cream interior buckets 350 stock v8 SS Cragars all way round. Loved it more than all the women in my life.
I know I'm late to the party - what's 3 years between gear heads, but just have to say my brother had one of those 70 Camaros and it was his pride and joy. You guys did such a great job "IMO" I had to forward the show to him. Now his wife's pissed cause he wants another one. LOL!!!!
Adjustment of the points is fun isn't it...I bought some new points , messed with them from about an HR...then put a different set that was used in it..ran just fine... thanks brothers. For a great vid.....!.. much appreciated.
One of my favorite builds on the show over the years !! A Beautiful 70' Camaro RS/SS Clone car, just please tell the people you sell it to later it is a Clone !! Lol : D
I think you should get some kind of medal for showing everything did not go entitely as planned. I worked for several years in a business specilized in restoring and servicing classic cars (in Sweden). In a big project, there are ALWAYS problems, no matter what money was spent or what people were involved. There are an infinite number of variables already with a completely stock car. Throw in some sub standard replacement parts and infinity is quantified... Hollywood productions make it all look easy. You buy some repop headlights and slap them on. Reality is boltholes differs, some metal needs to be shaved off or connector is wired for H4. I am much more interested in the obstacles in a build than the smooth sailing bits.
@Dave Micolichek not if they drop the distributor with the number 1 up on the compression stroke and didnt look at the pointer. i never do til i adjust the timing but not for the first drop and start
Man.....that engine start was very under-whelming. I've been waiting a few weeks for this engine start. Did they ever get it dialed-in before installing hood and aircleaner? I've seen old elastomer harmonic balance dampners get off on the timing mark due to the rubber drying out. They didn't even tell us what the issue was.
Yeah. They'll consider someone who can talk on camera ahead of someone who is skilled in this kind of work. That's why I'd rather watch a video of skilled people over someone being directed by a person behind the camera.
@@CharlieBrown-pb9xn Dude, if you are going to call people idiots, at least use the correct words. * "Their* as in their car. *They're* as in they're idiots.
It's strange but I've only ever seen that happen on Chevrolet engines - probably just because they are more common. A fix for this which should have been done would be to verify TDC on engine mock up with the balancer on to verify the correct timing marks. You can also do this on the car by utilizing a piston stop in the #1 cylinder and verify the timing mark is where it should be.
@@BBCharger5spd I'm a retired Ford Lincoln Mercury technician, and it happened with my 70 chevelle while street racing, and it came apart, and years later seen it on a Mercury Sable, while looking at it with a timing light. I reached down and grabbed it and could spin it....
Aftermarket companies like Holley, MSD, Edelbrock, etc. spend a lot of money on car shows like this, displaying their latest electronic ignition system or self-learning EFI, hoping to convince you to buy them. Yet this episode is BY FAR the best advertisement ever made for those new systems. Who in his right mind wants to spend all night scratching his head and singeing his eyebrows, when he could spend a couple hours pecking on a laptop instead?
I went back and looked and they didn't show them degreeing the cam in, so that is a possibility. I don't know BBC year to year small detail differences, but did they ever change timing tab locations?
I hope they used touch-up primer in the holes after they drilled for the SS Emblems !!! Trust me over time weather and crap "Will" get under the nice paint there from the bare metal !! It's an easy fix to stop that. : )
Why is it that no one on youtube or tv can properly install and time a distributor!!!!!..... I've been a mechanic for 22 years and have never had flames come out the inlet
I was squinting my eyes every time that thing backfired. I was waiting to hear that gas was just flowing into the Venturi's because the power valve blew
probably wise to go with a tall "truck" oil filter and put a heat shield on the exhaust there, it will hold about an extra quart of oil that way (in the filter!)
When the block was at the machine shop the deck was resurfaced. Did that effect timing or were the measurements redone with new pushrods? I know it's not an OHC, but still makes me wonder...
Valve adjustment could be off. My 454 valves were set to the factory specs but had to re adjust a couple of times to get it right. And remember carburetors were never “perfect”.
Nice car ..but I still have to grin when I watch these TV car shows trying to support the 396 legion, and this in spite of the fact that GM discontinued the Chevy 396 engine after most of the 1969 SS Chevelles with the 396 engine that started the 1969 Daytona 500 race, had either blown up or barely finished the race due to poor oiling issues. The first finishing Chevelle was a 1968 that finished the race 13 laps behind the winning Ford Torino Cobra of LeeRoy Yarbrough. After the 1969 Daytona 500 debacle, all of Chevrolets 1970 SS cars that came with 396 badging actually came with the newly modified 402 engine ...but GM never overcame the stigma of the 396 engine during that race. Just keeping it real..
must be nice having an early second gen camo......I'm pretty sure all 70 to 72 RS's have been outlawed in the south and hauled up north to succumb to Rust...because their is none down here at all.
I hate restoring to factory, could have had a 6 spd, rear wheel discs, and a rear suspension that could actually live behind a big block...long live restomod...
Edward Myers I’ve watched em for years...and I know they can time a bbc. I dont know why they even showed me picking up the distributor with the cap on and moving it though
I bet they had the idle way too slow + idle screws off , thats why it would run unless the timing was way to high. Notice they didn't say what was wrong. The Carb should have been Flow tested, I bet that would have done the trick.
Sure something can be defective, but no matter what I refuse to keep trying when a motor doesn't fire up near perfectly. I start rechecking everything that can be causing it rather than tear things up. Especially with a new motor I do not want to have it running at 200 rpm. Break in rpm is 1500 or better not 200.
Guys are all about selling parts brand names half the time they really don't know what you're doing read the filter box it tells you to turn the filter almost three-quarters of the turn and they don't even put the biggest filter on the engine that you can use by the way big blocks love to have the two quart filter on them big blocks circulate a lot of oil and I always used to line the engine up to top dead center and then put the harmonic balancer on to find out how far off the mark would be when I build engines with stock or aftermarket harmonic balancers once you get the ignition timing set you should only be off by 1 to2 degrees just learn how you set the timing on VW and you can set the timing on anything
I never understood the concept of “ saving time” by laying out the parts in order to how the install on the car. Didn’t you take the time to organize them and lay them out on a blanket on the floor? Time is time and it’s spent no matter how you look at
I simply love that motor manufacturers lied about performance just like they do today... Mustang 428 rated to 350bhp but actually 410bhp. Nowadays it's Mercedes C63 rated to x but really x-y
He says that this is just a 350 car. But I believe this is the first year for the LT-1 350. Which is the 375 hp 350 which is a bad mf. I would rather have the 350 than the 396 this year all day long.but they would never tell you that back then because they want you to pay for the more expensive option
They still haven't figured out that an L78 had 4 bolt mains, not 2. Not exactly competent putting the dizzy in and initial firing. It ain't rocket science.
Damn, Ive had distributors 180° out that didnt flame like that. I can initially time a motor/carb by eye that runs better than that. 🤣 My 70 Camaro (bought for 175 bucks in 1987) got put on a 73' 4wd Blazer frame and I raced it in the mud track. After selling the rest of the Blazer parts, the build was free, except for the $7K motor.
