Now that I do not know for sure. The member I built it for had all he receipts and passed them over to the new owner.
I would be glad to share the details of the build though, since I did put it together.
It's "just" a .030 over 360, I used the Sealed Power hyper pistons, since they require no special file fit rings. Stock resized rods and ARP bolts. Had the block zero deck height. Heads were milled to achieve 67ccs. Total static compression ratio ended up at 10.2:1. Stock 1.88 and 1.60 valve sizes with a basic three angle valve job. No port work. High volume oil pump and hardened intermediate shaft. It holds 40 PSI hot at idle and immediately slings to above 80 when the throttle is blipped.
I modded a set of stock 273 rockers to accept the Crane adjusters. Air gap intake and right now a Carter 625. It will have a Holley 670 street Avenger soon. Still running his point type distributor, because I wanted to break it in with a known good ignition system. And of course, the Erson cam described above. Cloyes true roller chain with a Mopar chain tensioner. I used the Comp 901 springs, so no machine work on the heads.
I think I remember him saying he had a tick over 5K in parts and machine work in the build......but he started out with nothing, so all the little stuff added up. But that includes everything such as carburetor and all, so it's about right.
