Don, The pistons are Keith Black Hypereutectic ( however it's spelled) The piston numbers I don't have in front of me, but I can get them. 1.6 Crane roller rockers and Jim at IndyMustang uses Scat cranks. It has a stock harmonic balancer, but the flywheel he sent me had to have additional holes drilled for the Ford Motorsports 10.5" clutch. It must have been an older flywheel. Anyway, they didn't center punch the holes before drilling allowing the bit to walk a little. In addition, the holder of the drill seemed to have difficulty holding the drill perpendicular to the flywheel. Drilled crooked, Tapped crooked. Flywheel on shop floor. Followed by call to Jeg's for a brand new Ford Motorsporst 28 oz. flywheel. I'm thinking of pulling the crank and taking the pistons out throught the bottom. Oh crap, just not thought the main bearings may interfere with that plan. Damn, now I may have to pull the heads. Well, we'll find out soon enough. I'll get back to you on the KB piston numbers and the actual cam profile. I'm starting to think it was easier for Indy Mustang to put a mild cam and save cutting reliefs for the valves than to go through the piston/valve clearance procedure. Any thoughts.
