Hi all, I have a 68 396, block casting # 3916323 with heads casting #3917215. It was a virgin block when I bought it with some minor cylinder wear. Bored .030 over to a 402 Std. Heads had no porting done, just new valves, seats and guides. I could not find forged pistons that were anywhere near affordable, so I bought Keith Black Hypereutectic pistons with Moly rings. Had them installed on the stock (non-forged) reconditioned rods. The crank is nodular iron. It cleaned up .010/.010 rods and mains. So, the big question, with the flat top KB pistons and the 101 cc closed chamber heads, what kind of horsepower can I expect with a decent cam, like a Lunati 60203, an Edelbrock Performer intake and 650 (or so) CFM carb? It is going in my 68 Chevelle (being resto'd). Currently, I don't have a new cam, intake or carb for it. Any suggestions??? Thanks in advance.
