Take a good look at the crank,if the engines a mash of parts someone may have put a forged crank already if your lucky,if not good used forged cranks are realtively inexpensive and easy to come by (I just sold one on e-bay for $185 shipped).It would problay be the same or cheaper than the mallory required to balance a cast crank neutral,but as mentioned you will need a internal style balancer and flexplate/flywheel.
