Is the crank diameter for the rear main seal the same diameter for the B block as the RB. I'm getting my crank cut and the grinder ask me to find our. They only list one for all big blocks.

I know the mains are bigger on a 440 than a
383. I would likely have put a 440 crank in a 400 if it was easy.
I just looked up the rear main seal in the Mopar catalogue and they list B/RB and Hemi as the same. I guess they're the same.

Just a word of caution. I think Id be a little worried about why your crank grinder didnt know.
