you guys have been a GREAT DEAL of help. I see the cons of this motor now. I'm still considering it, as i'm fascinated by the idea of a Jimmy with a Jimmy in it. I've never witnessed one with my own eyes. I understand the LS swap would make more power, but it seems somewhat of "generic" fix. Perhaps a 302 would be better suited to my 86' GMC S15 instead of the Jimmy.
Jay, I may take you up on your offer of a ride in the truck, if i decide to use a 302, i can tell you will be a great resource! Thanks for the info.
