SOHC, The 3.2 both styles and the 2.8, 3.1, and 3.4 conversion have nothing in common. 3.2 is an Isuzu motor. The others are variations on the GM 2.8 v6. They don't even share a common bellhousing bolt pattern. Not jumping your stuff but in the last couple of days I've seen you post like they are the same engine family so I thought I'd clarify.
