First, the 12-3/4" 153 tooth flywheel uses a starter with the bolt holes across from each other, 90 degrees to the crankshaft. The larger 14" 168 tooth flywheel uses a starter w/the holes offset diagonally from one another (see drawing below). | First, the 12-3/4" 153 tooth flywheel uses a starter with the bolt holes across from each other, 90 degrees to the crankshaft.

| − | Blocks from about 1962-up are drilled with three holes for either starter. The only two engines that may may not have the mounting holes to use either starter (other than the early blocks that used a bellhousing mounted starter) are the 200/229 ci 90 degree V6 Chevy and the SBC 400. The 229 V6 may have only the side by side bolt holes and not enough "meat" to drill the offset hole. The SBC 400 may have only the offset holes. It can be drilled for the other missing hole- but this needs to be carefully done for obvious reasons. | + | Blocks from about 1962-up are drilled with three holes for either starter.
