[QUOTE="Bad Company, post: 16874477, member: 141815"] If I remember correctly the Trinity 5.8 engine uses a different crankshaft due to the differences in piston weights, so there is a difference in the counterweight to balance the rotating assembly. I also think between the pickup truck 5.4 Triton engines and the 5.8 Trinity engines there probably is a difference in the metallurgy of the crankshafts making them weaker since these engines were never designed to produce 662 Hp. I wouldn't take the risk of using the truck crankshaft in one of these engines even if it drops in by adding weight to balance it correctly. The other major concern would be the snout of the truck crankshaft was never designed to turn a supercharger. The factory 5.8 crankshafts breaks the snout when a big supercharger is added showing that it is weak with the higher grade of steel used in making them versus the truck crankshaft. [/QUOTE]
