I am new to the LS crowd, but just a thought....will the ls 1 wheel fit the early long crank truck engines? It is .400 thinner than the truck wheel? There was a bit of confusion on the fit on the truck flywheel (Oriellys auto)....I told the gal, sell it to me (57 bones)....if it don't measure up, I will bring it back Yes, I did see that the 99-00, some had the long crank....not sure where it would put your starter gear, or clutch differences, but the ls 1 flywheel is .400 thinner than the truck pc? longhorn
