Since you have already had one crankshaft failure, I would purchase all of related rotating parts from the same source as your new shortblock (flywheel, clutch kit, balancer, timing set) so that in the event of another engine failure, no blame could be put on you for installing the wrong, mis-balanced, damaged from previous engine failure.....ect. parts on this engine. You might even want to go as far as shipping them your heads & induction system, & have them send you back a complete assembled, balanced, & dyno tuned engine
