Almost all 5.0 motors built after 1987 were the same except for a few parts. They all use the same block, heads, crank and connecting rods, the HO version got either forged or hyper pistons(depending upon the year) while the non-HO motors got cast slugs, but in all cases nominal CR was 8.8-9:1. The cam installed was somewhat vehicle specific, the HO got a unique roller cam while the trucks motor had a relatively small flat tappet up to 1991 that was switched to an equally small roller in '92 and then again to the "Explorer/F4TE" roller cam in '94. The intake, timing cover and water pump, oilpan and pickup, and accessory brackets are all vehicle unique too.
