Be careful, Slant flywheels (and I think SB too) have different size holes in the center for the register on the crank. '68 and up have a larger diameter hole than '67 and down.



Let's clear this one up right now.

The difference is NOT the outer diameter, which is all that matters fr a manual trans setup.

The difference is the inner diameter where the snout of the torque converter is supported.

This difference applies only to an automatic equipped car, not one with a manual trans. If you happen to have the early, smaller inner diameter crank and whant to run it with a later, large diameter T/C then you can machine the inner diameter out. If you happen to have a later crank with the larger diameter and you need to run it with a smaller diameter T/C then you need an annular ring to make up the difference. I believe Wildcat Auto sells them, among others.

They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.
