Sb 350

i got a small block 350 i want to put in my caprice......its got a high pressure oil pump, roller rockers, edelebrock performer intake.....the thing is i have tbi and i was going to put that on top of the performer with the throttle body adapter, but im wondering if the tbi will restrict the motor from running right....i want to be able to get as much out of the motor as i can.... i put a brand new fuel pump in the car and i didnt really want to convert to carb.... what should i do, or what would you guys do????....

also my car originally came with a 305 and someone told me the computer in it wouldnt allow the motor to run at its best, something about i would need a different computer or something.....does anyone know anything about that or have heard about that......Thanks for a response

change the computer or at least the chip to a 350 one
change the injectors to 350 ones(if you haven't already)

by using all the 305 stuff on a 350, it will run lean

the throttle body itself is the same. the 350 uses bigger injectors.
you can get a chip in the junkyard. find something that uses a 350 with the same part number ECM you have
