I just bought a used 5.3L engine that came out of a 2001 suburban and intend to drop it into my 2002 GMC envoy which currently has a 4.2L. This will be my first time doing a motor swap but will have assistance with the install. It has the wiring harness but no CPU... I heard I can "flash" the one that I currently have... I'm not familiar with the electronic sector of newer gen motors... Will I need to change motor mounts? Trans bell housing or adapter? Oil pan? What other components will I need to obtain in order to complete this? Any assistance or guidance y'all can give would be greatly appreciated!
Semper Fidelis,
