i have a plenum, runners and intake manifold, i'm thinkin all i need is the gaskets, fuel rail, fuel injectors, throttle body and air filter to complete this swap. would my camaro run well (or even run at all) if i did this swap without swapping any electrical makeup?

 

You need the ECM to operate the injectors as well as read the sensors, and as a result will need a wire harness tailored to teh TPI system.

You will need a fuel pump capable of delivering 3 BAR (44 PSIG) to the fuel rails and fuel lines which can operate at that pressure.

You will need the power relays for a TPI which may include a MAF power and MAF burnoff relay as well as the fuel pump relay.

There are some fairly detailed instructions posted in several locations on the interwebs.
