Today on Unity Motorsports Garage you get to see what I've been up too for the Past two weeks.
If you have been following along on Project SLEEPER: We have built a 408 Small Block CHEVY to look like a stock 350 crate GM crate engine from the early 1990's
This engine has to have a somewhat stock type idle and deliver the goods.
We picked up a old Holley Street Dominator intake manifold for $75 and I spent about 10 hours in porting it to @DavidVizard specs that he did over 40 years ago...
To top it off we are running a 800 CFM Q Jet carb.. Will it make Power?

Flipping the lid did not add 25hp, it simply removed the snorkel's restriction. Would have had the same effect going with an aftermarket 4" open filter. Great video guys!

Andy, I love your channel. In reference to the intake mods. I like what you did there between 5 & 7 to reduce the charge robbing there. I just wanted to remind you not to forget to do similar mods for 1 & 2 as well. There is a video of DV modifying a tunnel ram where I think he may have forgot about the 1 and 2 charge robbing, so if you would give him a friendly reminder.

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.

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!

Love to see yours with a 300-36 and a dually 454 stock air cleaner. Torque curve is perfect for a driver it will make huge tire smoking torque everywhere.

This is cool if you already have the 400 block to start with but the true 350 "sleeper" is the 383. The people who know wont be deceived by the valve covers alone. Cool build though and nice job on the intake and using a quadrajet carb for full incognito effect. Most builds go with holley type carbs if not efi.

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.

I had a 71 Buick GS 455, build to a stage 1 spec and with the 800cfm quadrajet, would make 460 horse and 550 lbs/ ft. As I started facing it, adding gears and better exhaust, fuel quantity was an issue. The quadrajet fuel bowl is really small, but short of fuel injection it's an awesome street carb. It gets a lot of hate though.

D*** good video showing showing what happens when you flip the lid, but then also keep in mind when the motors in the engine bag and the hoods close. And you're sucking in all that hot air off the engine. That's also got to make things a little great video. I'd like to have a feedback on the oil pressure situation. If you guys think that's a deal at all I just didn't like to see the oil pressure drop as the RPM went. I'd like to know what oil you have in it. Thank you, Greg and the team.Thank you again

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.

Always been curious of Dino results from a q Jet carb. 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.

Great job on the build guys. The manifold mods appear to be working well, and lastly I've always had good luck with the Q-Jets. You might double check the Q-Jet, it could be only a 750cfm? Look the bulge on the wall of the primaries and it's the 800cfm. One last test I would be curious what a stock Chevy or Edelbrock performer manifold Dyno numbers would look like? But that's definitely a strong sleeper motor but still nice road manners, good idle 👍👏

I had a pretty similar problem with the factory hydraulic roller springs on my AFR heads with a very similarly sized camshaft. It’d lay over around 55-5600 RPM. I swapped out the cam thinking it was just the cam being too small for the engine and a single pattern to boot, then changed the springs out too. The old cam is going into a 350 with the proper springs now so I guess I’ll find out whether or not it was the springs or the cam that laid over on me.

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

So back in the eighties car craft magazine told us that we were all killing our horsepower by flipping the air filter lid because it placed the top closer to the air horn. They also did an article showing us how to mount a nitrous bottle in an ice chest full of ice In order to chill it even further to cool the intake charge. That sure didn’t age very well.😂

Old timer had a 71 Lemans bracket car 3750lbs 400 ram air 3 heads flat tappet solid cam headers a single plane intake and Q-Jet……… the car had a turbo400 3800 converter 3.73 gear and it ran 11.40-11.50 EVERY SINGLE pass and without me asking he said “Its the Q-Jet”.

Love the build! Single plane is killing your torque though. When I had my 383 on the dyno that is now running EFI in my Express van, I had it running a later 850 cfm Q-Jet on an untouched Performer RPM spreadbore with a Hamburger 1" Q-Jet taper spacer upside down cone shape facing the carb. It has a mild hydraulic custom roller, 271/284 @ 0.006, 218/228 @ 0.050 on a 108 LSA and 106 ICL with 0.578 lift. 11:1 static compression and aluminum heads flowing 244 @ 0.400, 274 @ 0.500 and 291 @ 0.600. Ran with 1-5/8 primary to 2.5" collector Thorley tri-ys for the Express van chassis into 2.5" collector extension. Made 520 tq @ 3,700 and 502 hp @ 5,600. I had the HEIs mechanical advance setup to give 0 advance until 1,200, 10* @ 2,400 and 16* @ 3,600 by playing with an assortment of center plates and weights. The centerplate was 353 stamped and 053 weights, running 2 medium springs from a Moroso curve kit. It liked 33* total @ 3,600 and AFR was in the mid 12s. The 850 cfm Q-Jet saw less than 2 in/hg @ 6,200 rpm.

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.

It would have been nice to see what a 1 inch spacer would have done for the small plenum on that intake. It seems to have a much lager effect on small blocks than the big blocks. What do you think a nicely prepped 850 would have done. Maybe over 500 HP. 950 3 barrel was good for a tenth in a 69 Buick Skylark with a 455. Good test.
