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!

Wow that Q-Jet really is a performer. Great Dyno video. I knew my butt dyno was working right all those years, flipping the lid on the breather. The Sleeper is alive and working great.

Hell yes it's gonna make power! ...........quite a bit more than before anyway. ( Especially if the heads were ported to David Vizard's spec's! )

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.

Badass sleeper motah!! Yep, flipin' the lid, we knew it was a massive hp boost 35+ years ago, and still holds true today! That's the kind of hp gain you can absolutely feel by the seat of your pants. 💪

Thats what makes a street car fun Use some 20-22 in case Superturbos it will be quiet and quick. Love sleepy stuff

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 had a 400 out of a 73 caprice in my camaro. It was only.030 making it a 406 gota say personally I love sbc 400's! They're strong! Personally I had a different parts list but I know the potential of these engines especially the '72 and older 4 bolt main blocks!

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!

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.

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.

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.

I’m running a Progression Ignition distributor on my 353 small block in my ‘71 Camaro. Love it!

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.

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

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.

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+.

@@UnityMotorSportsGarage meaning good power for such a small cam 220 @50 on 400ish cubes

Is that top rear flap on the carb opening all the way? The engine will be fun.

Yeah David the QJET is wide open.. Thanks for watching Andy

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.

Doesnt need any more carb than what it has

Can't hurt to drain the break-in oil Andy. So the distributor was the problem?

The problem was the spade connector 12v supply going to the Distributor.. it was loose and causing the whole issue Andy

Awesome video! Now test a K&N air filter lol

If he did everyone would post K&N hate.

What would be cool is if the intake had been tested on a test mule motor like the series of test Eric Weingartner had done. Flipping the lid works on a motor pulling over 450hp..

@@UnityMotorSportsGarage ,,,,,,,,,,,Where are you in North Carolina?????

Love this content. Information I can trust from some of the best sources on the planet. My only question is- why not go with the AFR 210’s? Especially on a 400+. Everyone uses the 195’s, almost never see the 210’s on a dyno video. I have a 40 over 400 with 210 AFR with competition port. Is there a disadvantage I’m not aware of? Am I making a mistake??

Depends on a number of things. This engine would still run strong with a set of 180s on it

@@gordocarbosure it would. I just can’t believe there isn’t a video on KZread that uses the 210’s. Especially on 383+. 9 out of 10 times they use the 195’s.

Why does the oil pressure drop?As you rip it up it drops as much as 6 to 8 Pounds

All the videos with Chevrolet content may have some of your viewers concerned. 😂😂😂. The flipped lid should be your next shirt design
