The two flywheel wheel sizes are 153 tooth, 12.75” diameter. Used on 350ci and smaller engines, and the168 tooth, 14” diameter. Used on small blocks and big blocks, 400ci and larger.

Here is a good post by member "piecesparts":

[QUOTE]There are two sizes of flywheels/flexplates for the GM v-8 motors. There is a 153 tooth size and a 168 tooth size. The starters are designed different for these two sizes. The larger size uses a starter where the bolts are "OFFSET" to each other in the starter housing and on the block mounting pad. The smaller design uses a starter bolt pattern that is straight across from each other.

First take a look at your starter and see which one you have. Second, see if your block has three holes at the starter mounting point. IF you have the smaller flywheel design, then you will need to have the straight pattern on your starter bolts. Third, if it will make you feel better then mark your flywheel and count the teeth on it to see what you truly have.

If you happen to have a small flywheel, three bolt holes for mounting and the starter is an offset pattern, then change starters. If you have a small flywheel and only two holes, then you may have to change the flywheel.

There are aftermarket starters that have both design capabilities and it might be your advantage to purchase on of those, if needed.[/QUOTE
