not only will you have to swap the engine, but you will have to swap the PCM, all the wiring too it, and then may even have to have a PCM spacifically programmed for the swap. Nothing is impossible with enough money, but it won’t be as simple as swapping engines.

With something as common as a 2007 Gm pickup, your money would be better spent upgrading the motor that’s already in there.

A 4.8 is capable of making a good amout of power. A cam, intake, head work, exhaust and an ECM tune and that engine will be capable of making 350+ hp. Good thing about that is you can save up for each upgrade.
