Didn't balance very well?
No, it balanced out great. These cranks are very heavy. I had 3 options, internally balance (means new balancer and flexplate needed), drill the crank to reduce weight or drill the flexplate/balancer to reduce weight. I preferred pulling the weight from the balancer/flexplate as that’s less mass rolling around at the ends of the crank. Downside is the balancer/flexplate are now a match set to the crank. BUT down the road if I feel like going internally balanced because I decide this motor is going into something else and will see more rpm, the crank can be balanced that way without needing anymore added mallory or tungsten from drilled counterweights.
