LM7 truck ECM compatible w/Holley EFI?
I have a stock 5.3 truck engine/4L60 sitting in an 56 Chevy. It had a Holley EFI throttle body on a Holley carb style intake when purchased. Is this compatible with the GM ECM and if it is what general mods need to be made? I am sure the computer will need a re-flash as well. I am new to his modern stuff.
Thanks, Bob
