I am assembling my 440 and I have a question about which balancer bolt to use.

It is a 1976 cast crank 440.

One bolt is approximately 1.25 inches long

The other is approximately 2.00 inches long

Both measurements are taken with the washer off.

One could be a SB bolt. I don't want to bottom out the big one and think things are tight etc.

Any help here?

Thank you for your support.
