From another thread...
This is exactly what I was thinking. A cursory look at the shop manuals seems to indicate that there are only a few wires that are different. I have Tunercat SW that allows programming, including changing the VIN in the PCM (which I am assuming will be required to allow the swapped V8 PCM to talk with the BCM and the rest of the modules.)
I presently also own a 2005 Silverado Crew with the 5.3, that actually uses less gas than my 4.2 TB.
I haven't hit Scarab up, yet, but I was wondering if anyone else had done this.
(This is not something that I'm afraid of. Just looking for potential "gotchas" that others may have experienced. I have done several swaps over the years. I presently have a Fiero with a Caddy V8 in it, mated to a Baretta 5 speed. Fools rush in... )
Thanks,
Steve
ScarabEpic22 said:If you wanna do a 5.3 swap, hit me up for how to run the PCM setup. Its a LOT easier than we all initially thought, remember the 03-04 LWB trucks came with 5.3s...run a 1MB LS1B PCM, flash the correct OS (a 5.3 TB OS), and do the wiring to match that of a LWB truck. Retain ALL creature comforts plus get a 5.3 (or whatever V8 you wanna throw at it, just adjust the PCM correctly. 4.8, 5.3, 6.0, 6.2, even a 7.0L ... [6.2, 7.0L need a converter box]).
