A buddy used a 2004 truck 5.3 computer with the motor and pedal assembly in a 69 Camaro swap he did. Is there any thing other that VATS that needs to be changed for it to start? Motor is completely stock other than headers and air intake. I thought the truck computers did not have VATS but after looking at a stock truck computer I guess they do. I have worked on a lot swaps using fbody computers but not too many truck computers or drive by wire.
