My main concern is parts compatibility. I have a good 4.4 engine I can swap parts from. I heard the exhaust bolts on the head are drilled differently on a 4.8 than the 4.4. Anyone shed some light on this?
I can swap my oil pan, headers, and any other parts that would be different. Would I need a 4.8 engine harness? I think the dme is also different.
