Thought the 92's went over to the hyper-junk pistons, but the larger B303 style cam? Maybe I'm wrong, it's been a second since I've touched a fox body. Now if you come across some ford explorer 5.0 motors, yank the heads, and the lower/upper manifold. We just got done tuning a 91' with a Vortech S-trim, Trickflow top end, and a built AODE. Little 3,000lbs bastard belted out 445RWHP with some timing left in it. We started hitting around 320-330RWHP.
