basically rebuilt only what it needed, exhaust valves on the heads needed to be replaced, the crank, connecting rods, and heads were fine. Changed the 509 cam out for a more street friendly(will get specs). While the motor was out, I took advantage and picked up a 2400 torque converter and will unload the 3500 stall that was in her.Congrats & have fun, it will be on the road soon... What was the engine build details ???
