I got an 89 IROC 305 TPI, could i take my manifold off, slap that baby on and get decent horse power gain?

 

If your motor is stock you wont see a huge gain in hp but you will lose some bottom end and if you dont plan on upgrading the rest of the motor and dont see alot of track time i would stick to the stock intake and spend your money else were

 

hmm, man i dont know what to do.... what can i do to soup up a stock 305 tuned port?

 

start with a cam and some major upper pleneum porting

 

Start with every free mod you can do[which are listed a few threads up]then make your own cai and then get a full exhaust,stall and a small cam and you should be content until you can save up more money for the good stuff

 

look at my sig.
