'74 Duster big block conversion
Crank is in. I used the ARP main studs and billet rear main seal cap from the 440 along with a new red Viton rear main seal. I have had really good luck the Viton rear seal not leaking on multiple engines, even after sitting for a while. The main studs are probably overkill for this build, but WTH, I had them.
