well i am looking at building a 383 and i am not sure what i crank i need.these are the part numbers for the 4 that i am looking at they are in jegs 942-435050,942-435056,942-440056.any help on which crank is right or which one would be easier to clear and balance.thanks again for all the help.matt

If you are using a 2 pc rear seal 350 block. Either 942-435050,942-435056 will work. But you have to know what rod length and pistons you are going to use.
