1976 engine build hood clearance
Been lurking here and very helpful. I am having a hard time finding a good combination of edelbrock heads intake and carb maybe holly for the stock 350 that is stroked via scat to 388. Told that air gap won't fit and any other intake will strangle good heads. Don't want to change hood. Now has Dart stock type iron heads with edelbrock intake and qjet about half inch hood clearance to stock air cleaner. 340 torque and 285 hp on dyno and went to 2400 stall transmission so ready for more hp at higher revs. Help. Thanks.

I have an rpm air gap with a quick fuel carb. Do have a chevy performance air filter with a 3inch drop. have a k&n 2.5inch filter and enough clearance. Had a 3 inch paper filter and still was fine. I do have the insulator pad in place, removing it would give more precious area. make sure you actually have a 76 hood. the 76 hood had a higher rise than earlier years which allowed more room for mid rise intake manifolds.

Hi rosros: I think the hood is stock 76, everything else is. Maybe the problem is the heads being recommended Edelbrock e-210, with torker II intake because thought air gap would not fit, but would rather have air gap. What heads does your 76 have? Could be this can be solved with the air cleaner you are talking about with 3 inch drop. Thanks

I have Trick Flow Super23 heads. You can do the play doe on your current set up to see how much room you have. Add the intake height, carb height to get a fair idea. From past experience, my shop knew the rpm performer air gap will work. the regular performer air gap no problem.

When I had the stock hood I went with the wieand action plus, probably not as good as the performer, but still made 258 rwhp with it. If your buy the intake from shucks or oriellies or such, you can trial fit it to make sure that it fits, When I built the new engine I replaced the hood with l88 high rise so that I wouldn't have to worry about what configuration I ran. Good luck on your project.

nother thing that needs to be taken into consideration here is the clearance between the top of the air cleaner and the fuel bowl vents. Conventional wisdom says to leave at least 3/4" of space, and more would be better. A carburetor works using atmospheric pressure on the fuel in the fuel bowl. When air speed through the venturi gets high enough, it creates a low pressure area, which allows atmospheric pressure to push fuel through the circuit. If the air cleaner lid is too close to the fuel bowl vent, air flowing past can create a similar low pressure area over the fuel in the fuel bowl, lowering the "push" on the fuel in the fuel bowl, affecting fuel metering, especially at higher engine speeds. An easy way to get a rough estimate of this clearance is to remove the air cleaner lid and filter, and put the air cleaner lid back on, allowing it to touch the top of the carb, and note how much more of the air cleaner bolt is sticking up through the air cleaner lid. If you have a 1.5" dropped air cleaner and a 2.5" filter, the air cleaner lid is probably very close to the bowl vents.

I went with a Weiand low profile intake and have ZERO clearance issues, running a Edlebrock 600, with 1.5in air filter drop pan and a 3in Air Filter. Not sure if its a coincidence or not but my engine also runs at 190 degrees vs this usual 200-205ish.
