454's are different.  350's are internally balanced, 454's are externally balanced motors, which require a balanced flexplate (flywheel).
86' Chevy Step Side, 548 BBC, TH400, 18" SCS Tcase, 4 linked, 18" King shocks, 16.9-26 R1's & R2's

400's and larger are all externally ballanced and have a ballance weight on the flywheel, ya need one for those motors, their not expensive, ya can get one from summit for like 60 bucks
