I have a 2011 Chevy Express Van 3500 with a 4.8L. Some thing let go in the top end. I picked up a used 2008 4.8l. The question I have is the 2011 has vvt and the 2008 don't. Will the 2008 run with out vvt hooked up with the 2011 wiring and computer? Or do I need to swap over the timing cover, gear and cam?
