NEED INFO! 383bb PLEASE

It had the 383 w / two barrel but it had the cast crank. Be sure to identify which crank so you can be sure to use the torque converter that has the proper weight's on it. If you don't want to fool with the proper toqure converter, you can always find a steel crank. Either way, I would have the engine balanced at a machine shop to ensure longevity. Not to mention, well I guess I am mentioning, that an engine that is better balanced, isn't robbing HP to run itself. If I remember, the balance only cost about $150.
