Is it TBI or TPI?
An IROC should have been a Tuned Port Injection system not a Throttle body Injection.
IF it's a TPI system, you'll probably have to change the injectors to higher flow injectors and get a new chip for it.
Be careful not to run full throttle or you could burn a valve.
Post more info and you'll get more help.

THE VIN E 305 ENGINES HAVE A THROTTLE BODY. THE F 305 ENGINES HAVE TPI. I HAD IT HOOKED UP TO A SCANNER AND NONE OF THE SENSORS ARE BAD. FUEL TRIMS WERE SHOWN AS:

RPM 2500 1500 625
SHORT TERM 134 134 129
BLOCK LEARN 172 172 161
