I have a 68 firebird with a 1974 code engine block and heads, I bearly have any hood clearence and as a matter of fact the top of the air cleaner cover presses against the hood insulation. I run a pretty short air cleaner. Is there any difference in the engine height or maybe the engine mounts?

On a seperate note I have the original 4 piston calipers on my car. I have to run a quarter inch spacer so my wheel clears the caliper but then the wheel hits the fender when i hit a pot hole. Are there any wheels that clear the caliper without a spacer that are 15x7 and not original rallys?

Any help would be appreciated

All Pontiac V-8s have basically the same dimensions. The 74 may have had the odd bolt hole configuration that doesn't accept the standard 1st generation mounts. Someone probably fabricated some mounts. If this is the case you can straighten it out with the correct kit. There usually is a lot of clearance between the carb and hood.

What intake do you have? Also the style of air cleaner- does it sit on top of the carb or go down around it?

The engine mounts are correct for the car and the pully is as low as possible (just bearly above the sub frame) I have an edlebrock intake on it right now. As for the air cleaner it just sits on top it doenst go down around but maybe an 1/8 of an inch. Are they supposed to have a deep pan?

Check the clearance between your oil pan and the cross member. It should only be about 1/4".

What are you refering to regarding your "pully"?

They make air filter base plates that will drop 1 to 2 inches down around the carb. (this came up earlier today in another thread) There are also air filters of different heights...

With a flat hood you will need a drop base air cleaner.

ditto to vikki's post! but another thing that might interest you is the new fiberglass cowl hoods. they give an extra 5" of hood clearance.ii have both a cowl hood and a flat ohc hood. i think ium going to go with the ohc hood for now because it gives a more docile appearance to the car. people look over and see the 6 emblems on the hood thinking ive got a puke bucket only to find out i have a monsterous 455between the frame rails!

Thanks everyone i appreciate the help. I will start looking for a drop pan for my air cleaner.
