5.3/ 4L60E swap

[Phil's 70]

Has anybody out there done a complete swap in which they put a 5.3 vortec and a 4L60E transmission into one of these trucks? Does anybody have any knowledge of how difficult it really would be? I am talking about a complete swap engine, transmission, with computer and wireharness. Just looking for feed back about this.

If peole need to know I running a 350/ turbo 400 trans right now in a 70 chevy 1/2 ton.

What modifications to the wire harness did you have to make? what company did you use to reprogram the computer?
