"you don't need to run the lt8s in parallel with the stock ecu. there's nothing good about the stock ecu anyway... if you have a good tuner you can get the same driveability and reliability as the stock one. if your going to convert engines into your car you can use whatever computer and wiring from that car to run in your car... if you can figure out what does what, and wire in the appropriate power/ground/fuel pump/signal wires into your existing car. the question is, if your going to go to all the effort of swapping in other engines, why the hell would you use a stock computer in the first place? if its to save money, then don't bother swapping anything, as trying to put something into an engine bay that wasn't supposed to be there in the first place is always gonna cost plenty of money no matter what you do. spend your money on the engine you have, get a set of decent cams, extractors, the lightest flywheel you can find, and a fuel system, combined with a good suspension system and you will have yourself a fun car to drive.
