Default 153 vs 168 tooth fex plates?

I understand that each of these flex plates is different in diameter, the 168 tooth being the larger. How do you know which one shoud be used in a given application? I presume that it's related to the tranny and torque converter rather than the engine, but there doesn't seem to be any consistency.

Anyone know which one was used when? I need to figure out what's wrong with the starter on the 73 (TH400) and I'd like to verify that it's the right one.

168T ... assume it's for your L48 ... so specify it's for sbc 350 ... BBC454 & sbc 400 are different.

Correct, it's for the L48 350 with a TH400.

You're right, it may have nothing to do with the starter.

When you engage the starter, it makes a horrible, metalic clanking and ringing sound. One of the obvios checks was to see if the correct starter and flex plate were used.

I believe your starter will determine which flexplate you need..mounting bolts straight across should mate with the 153T....
