Ok. Can you use a 146xf tooth ring gear on a 270 gmc flywheel? With stock starter? If not why would Schiefer put one on a gmc flywheel? Or what starter is used? Or, is there another 4 bolt crankshaft that uses a 146 tooth ring gear? Or am I completely wrong and it fits a flathead mopar 6 or 8 from 40s or 50s? Any ideas? Want to buy this one on evil bay but unsure what the deal is? Help! BTW 40 and earlier chevy had the same a GMC too. Posted using the Full Custom H.A.M.B. App!
