Go ahead an get another crank pulley....
I have a few good ones at my shop.....
motor mounts were replaced when the new HB was installed amongst other items so I believe them to be ok, I went looking at them yesterday in the rain and didnt see them from the top, I will get under it to verify their condition. The crank pulley has new bolts in it so it should be easy to remove. So would I remove the HB as well and take it to a shop for balancing? Or is there a garage method?
how much you letting those go for
Suggest replacing the crank pulley with a zero balance aluminum pulley. Several of the vendors sell an underdrive pulley kit that includes a smaller crank pulley and larger waterpump and alternator pulleys that will correct the wobble and balance issue, and provide another 10-15 HP at the same time.
Or you can purchase a 10% OD crank pulley from MP that is zero balance and larger than stock on the blower drive portion. I believe that at least on of the vendors is selling a stock size aluminum crank pulley that is also zero balance. I wouldn't bother with trying to balance the stock stamped steel pulley.
