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?
that shouldn't be a problem , if the counterweights are still the stock size leave them as is and notch the bottom of the bores , doing this you should be able to internal balance and not have to add an mallory . even if you have to add mallory the last thing i would do is external balance a performance engine .
for reference , the last set of those diamonds i had , with a manley sportsmaster 6.765 rod and .990 pin the bobweight was 2282 grams
