Gee Martian--give me a little credit here. I'm the PM at a GM dealership and I pulled that info straight out of their parts catalog. It's originally out of a 1990 only 1500 truck of the older (classic?) body style. GM changed to a newer body style in '88 which means this motor was originally in a 1/2 ton cab & chassis config or more than likely one of the last full size Blazers.
