Your computer may or may not need an accelerator petal interface (some did some didn't). The only difference between the 4.8/5.3 engine is the stroke (different crank/rods/pistons) The 5.3/5.7/6.0 engines all have the same stroke (crank/rods/pistons) but the bore is different for each of these engines. The 5.3/4.8 electric throttle body is the same - I used 4.8 parts on a 5.3 that I helped a friend wire up and it worked fine.

Beautiful! I will grab all I can off the 4.8. Dug
