Recently I've been considering about a real engine swap. From the Lo3 to a 7.4L 454.

I originally was going to do the carb thing, but then started thinking about those 454 SS TBI's that were available in the early 90's.

Does anyone know if the stock Lo3 TBI wiring will plug & play with a 454 TBI engine?

I'm more or less wondering if I would have to rob the truck of the harness and computer box.
