Ok..i now have an 89 Jimmy 2wd as well as my Blazer. The Jimmy has the 4.3 in it right now and that engine is shot. Just to recap what all needs to be changed to go to a V8. Mounts, ECU or at least the Prom chip in the ECU and replacing the belt driven fan with an E fan? I would be using a TBI V8 when i do this. And its a 4.3 TBI if that helps.

easy swap, pretty much as you say,just be careful over there on the passenger side where the computer wires go back in the cab, its "real" close if you set the motor all the way back.
