Okay heres the deal. I have a 74 block 454 with a 14 in flexplate 168 tooth. I currently have a Tilton starter that the PO put on that has the gear teeth worn down due to improper spacing. I can't use a standard reman starter cause the offset mounting whole has been drilled out as if to install a threaded insert yet has no threads. I had a shop look at installing a threaded insert, but they said they can't cause the hole is out of round and they are unable to fix it. So I am trying to find a replacement starter that will fit. I don't want to spend the money on an aftermarket high torque starter so I am looking for a factory style starter with the straight NOT staggerd mounting wholes. I have found the following options and hope someone can tell me if they will work. GM performance parts #1876552 HD reman (about $98) listed with Scoggin Dickey Parts Center as for SB v8 and 90deg v6 and list the flywheel/flexplate part numbers that it is compatable with all are 14/168. The pic in the mag shows strait mounting pattern. Or I have looked on partsamerica.com (tried having the counter guy at Advance look in their parts book to cross reference a part and he couldn't figure out anything. Didn't even know how to use the book just looked at the pics.) Anyway the website shows the 3664S starter (about $30) with strait mounting for the following vehicles 71 P30 w/454, 68 C20 w/396, 68 chevelle SS w/396, 68 Impalla w/427. Now all of these except the P30 show a 14/168 flexplate/flywheel. The P30 doesn't show a flexplate/flywheel listing but I assume it would be 14/168 as well. Now would either one of these options fit or should I just get the Tilton rebuilt ($100 local shop) I really don't need the high performance aspect and will be replacing the engine within the year at which time I would be able to buy a regular offset mounting starter again so I can't justify spending more than $100 on it now. Please help!
