Ok guys, I'm starting to look for some parts to get for the new motor. Thx to
@treehan77 I got the knock sensors--now I need (possibly)heavy duty or double timing chain, a Melling--or GM--oil pump--high volume?--thermostat, gonna use my same water pump since it has barely 20,000 miles on it, knock sensor harness, oil presdure sensor, the usual gaskets--intake, oil pan, main seal etc. I've already bought new lifters and trays. Still not sure if my old BTR cam is still good. If not, that's $400 right there. Anyone have any suggestions or comments? Especially about the timing chain and oil pump. Thx guys. Anything I'm forgetting?
