No, this was a customer motor. 440 based 512, 440-1's, Eagle rotating assembly as I recall. It had stickers from a rather widely known Mopar shop on it, the guy blew it up supposedly on his 1st weekend after getting it back. Based on the rust, I assume i was sitting for a bit, or maybe the shop just doesn't GAS enough to bead or shot blast parts.

I don't use stock main caps for anything other than stock headed builds. I don't build for other people, I just machine parts, but that's my 2 cents. S/F....Ken M
