I'm considering buying a new 2004 RC/SB 4.8 5speed(or possibly used if it's worth it, the 2004's are very cheap right now) with the intention of swapping in a 6.0 or LS1 and 6speed. Can anyone recommend shops in the SW(AZ, NM, W-TX) to do the swap? I'd love to do the work myself but I really don't have the time or place to do it right now. I apprecaite any help you can give me.

 

dont know of any shops but good luck on the swap. I would love to have that set up underneath my blower with a 6speed.

 

any automotive shop could do it. IT is a direct plug an play install. the only difference will be the wiring harness setup for the 6speed

 

hope that helps.
p.s it will only be a plug play if you have a 4.8 or 5.3 to start with.

 

you'll need to get either a 5.3 computer from a wrecking yard or because you need to adjust the comp for the 6speed you can reprogram your 4.8 ecm

 

Arizona Speed and Marine is a great shop in the SW to do the swap. Give Ben a call over there at 480-753-0208.
