heads (gt40s), cam, rockers (rollers), intake, injectors (24lb), maf (bigger), computer, maybe a couple little more odds and ends. short block is the same as the lx/gt 5.0 for 93-95 (hyper pistons instead of the earlier forged ones). that said, it'll all bolt into a regular fox except the maf and computer (calibrated to each other, so use a meter calibrated for 24's with the stock a9_ pcm or run the stock 19lb injectors)
