What rod journal size? 2.20 or 2.25?
I have a SM 4.25 stroke 3.25 main with 2.20 rod ends. New in box, never used since the 455 block I got was cracked. I’m about an hour drive away from you. PM me if interested.

I bought a 3” main 4.25 stroke from SM some years back and had to return it cause the RJs didn’t match the listing.
