I'm trying to put together a rotating assembly for a 400 small block and can't seem to find the bob weight anywhere for a Callies Dragonslayer crankshaft. The piston and rods minus the bearings and rings are going to weigh approximately 1267 grams. I just want to be sure that the crank is on the heavy side so material only has to be removed. I'm thinking 1600 grams to be safe. I've searched and can't find anything on sbc Callies crankshaft bob weight.

 

Bump.
