I want my 94formula firebird to have around 350 horses.

All I have is a K&N intake and flowmaster..

What is some other mods that would push it to 350?

 

I think you could do it with a mild cam and some self ported heads if you know what you are doing, but I think it would be pretty hard if not impossible with just bolt-ons. Some long tubes will probably get you the closest out of any regular bolt on stuff, but they'll set you back over $500.

 

Not going to happen with just bolt ons, unless one of the bolt ons is a bottle or a blower, LOL.

Every bolt on in the world will get you to ~300rwhp, maybe 310.
