I know this may sound pretty dumb, but it is all about dollars. I need to replace/rebuilt the 350 in my '86 Jimmy. I have access to a '94 Chev 1/2 ton pickup with a 4.3 in it. the rear end went out of the truck and then they blew the front getting it home. So it is a complete donor vehicle. I figure the newer V6 puts out about the same power as the carbed V8. I know the trucks history and the engine is in good shape with 84000 miles. Give it to me straight.
