Dan had the original numbers matching block machined to .040" over and had the decks trued and squared. Forged Eagle H-beam rods and Icon flat top pistons replaced the stock cast pieces. Since he had a few Summit 2800 cam & lifter kits around, one of those was installed with poly-locks. The 6X-4 heads were cut enough to clean them up and ensure good sealing and has new Ferrero valves and springs. The pistons are .005" out-of-the-hole, so Felpro .045" gaskets were used to get .040" quench. The static compression calculates at 8.75 to 1, so 0.65 above stock. Since the TA already has an exhaust system designed for factory SD455 exhaust manifolds, Dan elected to use '70 D-port RA manifolds in-lieu of the original logs. The engine gets broken-in next week and hopefully to the dyno before the end of the year. Dan's hoping for 350 hp and 450 lbft torque, so we'll soon see.
