I have a 91 Formula and Im gonna swap out the 305 for a ZZ4.
Am I gonna have enough clearance with the stock hood?

 

depends on your intake and air cleaner choices.

i do not know i am have the same question do you think this will fit under my hood it looks way too tall. http://firbirdgta.tripod.com/cars/id8.html

its a 350 with preformer rpm intakemanifold and a holley tbi
oh yea i have a 92 firebird

 

I want to use the performer RPM.

 

carb or tbi?

 

I'm gonna go with a carb and drop the tbi.

 

u should have enough clearance if u use a drop base air cleaner assembly, it worked in my camaro with a rpm manifold and holley carb, unless the camaro has more hood clearance than the firebird, if it does i don't think it will work cause mine was just able to clear.

 

I've got a TA-84 with the bulge on the hood. I installed a 355 with Performer RPM intake and a 13x3 inch drop based Mr. Gasket chrome air-cleaner. When I closed the hood it touched the ram-air system. I removed the plastic stuff and also the hood insulation and carefully bent the sheetmetall flange that the ram-air system was attached too, just about 1/4 inch or so. It fits and look great.

I was able to close the hood even with the ram-air system in place but the torque from the new engine makes it hit the ramair if you don't remove it.
