I'm looking for either the i6 or 304, both I believe came in the 84 cj7. I know the 304 was more prevelant in the 5's, but I think it came in the 7s as well. Also need some ideas on which would be better, as this is my daily driver and all that "inspection" BS still applies. ANyone out there wanna do the actual swap? If so, at what cost? Cash or beer? etc.... I'm hoping to buy maybe after Christmas, so keep me updated.
