2008 Avalanche 5.3L to 6.2L VVT Swap?
#1
My 5.3 is having some issues and I'd like to swap to the newest L9H engine with VVT. Is there any way to retain the VVT or would I need to disable it by putting in a new cam sprocket? Is it possible to put a newer 09+ ecm in my truck and just tune accordingly? I've searche but info is sparce.
