6.0 or 5.3 swap for a 4.8

04-15-2013, 08:31 PM

We have an '01 GMC with 99,000 where the body and interior are immaculate. The engine is starting to use a little oil and honestly doesn't have that much "get up and go". Will a 5.3L or 6.0L bolt right in using all existing components? I know I may have to deal with the computer but other than that can we use the coil packs, drive belt and accessories, etc.? Thinking about picking one up and doing a swap. Any advice from someone who has gone through it would be appreciated. Thanks.
