What is the best way to get more horsepower out of my 305 in my 87 firebird formula?? I'm getting a huge air cleaner and having dual exhaust installed. Is it worth it to put headers on, or is that just a waste of money??

 

A good way to get more horsepower is to open your wallet Headers is a good way to start. If you're getting an air cleaner I would guess you have a 350 TBI car. You should get a good catback exhaust system to go with the headers, then maybe a different cam, intake and throtle body. I heard the ones off the 454 trucks are bigger and can flow a lot more air. Try to post this in the TBI board.

Truth be told i have had many cars alot with headders and i have never noticed any difference in power or economy like the manufacurer says. i paid 800$ for custom headders for my departed 67RS and my Quarter mile times stayed the same. I would try a power chip if you have tbi that will improve performance compared to what headders are supposed to do.

Any stock 305 is going to wake up nicely with anything other then the stock headers! Headers, intake manifold (TPI?), 1.6 roller rockers, and a higher stall (2800-3000) converter are about the best mods that cost under $500ea that work well on a 305 that can be transfered to a 350. Heads are a waste on a 305, at that point just go with a 350+ shortblock too IMO.

Spray or supercharger are good ways to make power too.
