Ok. I want to use the 383 block sitting in the corner. How about the cast 440 crank with the mains already cut for B motor I already have? (I also have a NOS 440 cast crank) Has anyone built a 431/383 with a cast crank? How much did you turn off the counterweights? What rods? (LY or aftermarket?) External balance damper? External balance convertor or flexplate? How much mallory?
Hopefully I am on Todd's list and I want to start gathering pieces that I don't already have.

Do I break out my spare 915's, my B1BS's or my Stage VI's?
