fuel system
 

I own a 1986 i-roc z28 tuned port injection that has a 91 corvette 350 motor swap, wiring harness and ecu..... Im haveing a problem breaking 300 horse which I belive is due to my fuel and ignition system . The motor is worked, its bored to a 355,cam, hydraulic lifters,billet rollers,valves,port and polished heads andintake manifold, headers, highflow cat, 3 1/2 exaust, and a K&N intake. I have also removed the a/c and smog system. Iwould like to upgrade my fuel and igniton system including injecturs, fuel pump, fpr andand msd ignition.The problem isI don't know much about this stuff... Ifanyone could helpplease email me @ xhardknockz@yahoo.com or post an answer on here. thanks

RE: fuel system
 

The TPI is very limited on airflow possibilities, The only thing to do is to get an aftermarket intake, runners and throttle body. The engine is an air pump and the intake system is the restriction.
