I love these Chevy builds. I’ve done a couple 400 builds for my 83 Monte Carlo. Might not be impressive on the drag strip but out on the open highway nothing can touch it. Always enjoy watching people freak out over the car loosing traction at 65mph because I decided to get on it. Always wanted to do a progressive nitrous setup on it. I believe that would help the stock sleeper idea.
@patrickm.84258 ай бұрын
Not sure who wouldn't find this impressive at the drag strip, but not all of us have to live on LS's and turbos, some of us still like seeing what we can do with N/A and using our heads. This engine is a low 11, high 10 second engine in anything but the heaviest cars at the track. Look at it, and with a Q-Jet, that's pretty damned impressive to me!

With the Q-J, double check the air flap's spring setting - Been a few decades, but IIRC it should be either 3/4, or 7/8, of a turn from JUST closing the flap - an 1/8th either way could also have been enlightening. Don't know if you did it, or if the heads you used had them, but a couple of bits of shim stock slipped down between the manifold and the heads, to block them off, can help a little by reducing the cross-heating of the manifold base.

Not too bad for a first run gotta start some where and go from there. The lid flip didn't surprise me I've done it many times over the years and I always could feel the difference on the street. I know the quadrajets becoming a restriction do to flow size, but the cam needs to go for a better spect one. Run it with a better cam and the quadrajet then just to see what it can do put a higher flowing spect carburetor on it. Personally I'd be willing to give up some of the power just to have that nostalgic Quadrajet sound of the secondarys kicking in, and fool everyone into thinking it's a rather stock replacement engine.

Don’t know if “flipping the lid” actually did much other then giving the carb more area to draw air from instead of making the air route through the small intake hole in the filter housing. Maybe an open air filter would do the same as flipping the lid. The drawback would be loosing the sleeper look though.

Back in the day when I was broke I had a 780 cfM Q jet 331 cube Small block.That pulled hard to 7000 Only reason I put that carb on there is because it was a 150 bucks at my local auto parts store rebuilt and But I was a broke 19-year-old kid the was no save up for 2 more weeks. That 69 GMC had to out an get in trouble. later saved up and put a holly 750 double pump on it. Cause my buddies are laughed at The bog quad But it actually ran better with that carb than it did the 750 holly out of the box. And it got good mileage. And every classic movie sound has that noise from the 80s All the caprice cop cars. They were great carbs as long as they sat on a good loom intake and had no fuel boil issues like the stock cast intake. I love them and the sound they make In the secondarys open. quick throttle response can't beat it.

But I learned from the first one I had that if you are on top of it and don't let it go to the point that it would need bored between refreshing they will last. I would like to go back to getting one in something but I have went to FOMOCO now and I don't want to go back. I have bought a rust free 1988 Mercury Cougar XR 7 from a 90 year old guy and his son. They threw a fuel tank, fuel pump, sending unit, new fuel lines and 8 new injectors in the 5..0 L and I bought it for 700$ before they scrapped it. Luckily I was at the right place at the right time and saved it. Wait until you see it, it looks like it sat in a dealership somewhere since it was new. The interior looks like the day it rolled off the show room floor. I can't wait to get it done and running. Great day to you all Andy. Sincerely John

Use the moroso oil filter screen and save your oil filter doesn't affect flow and easy to check and replace

Can't hurt to drain the break-in oil Andy. So the distributor was the problem?
@UnityMotorSportsGarage8 ай бұрын
The problem was the spade connector 12v supply going to the Distributor.. it was loose and causing the whole issue Andy

Looks like y’all are close to me because I saw the Charlotte hwy sign. I’ve dreamt up a weird idea. I could care less about high crazy HP. I saw an episode on horsepower tv where they turbocharged a big block ford for torque. I want to turbo my 350 TBI with a small turbo to get as much torque as possible. I also want to do it with the TBI. I know there’s a lot of haters on those things but they just work and keep working. Anyone I know personally that has a TBI 350 is still running the original setup. There’s upgrades you can due to them and on the cheap. My thinking is what’s the point of getting a aftermarket EFI if your goals aren’t 500+. Plus I’d get a kick out of seeing a TBI pushing 400+ torque.

@ 1985 or so Chevy came out w/that throttle body w/the injectors on the "carb." Basically Chevy's quick fix to have quick easy F/I. Is this viable for extra HP? Your 408 SBC could say 2 of these be used to make a significant HP gain? Worth the head ache to play w/these old F/I system or not?

If you notice the receptacle on the wall is GROUND UP. Why is that significant ? According to OSHA that is the legal & proper way. Look between the door jam and the window.
