    Hi wanted to know if u really have t rebalance ur rotating assembly. Had a lighter alky crank around 2700 but now got a A fuel crank of 3000 bob weight. I know it’s best t rebalance but I am only turning it to min 7000 t max 8000 at best in a low blown alky deal to run my altered in the 7:50 class?? Thx

    Does crank have heavy metal that can be removed? You should rebalance. Removing weight is a lot easier than adding.

    A couple of grams would be good.
