On the BHJ I hear differing opinions about balancing the pulley to the balancer. Is this neccessary? I pulled this off another forum:
""""If you look at the current FAQ on this basically the thinking now is that the balance pins are not used to match balance the pulley to the damper...they were placed in there to dynamic balance the entire engine assembly as well as pins in the flywheel or rivets in the flexplate.
So to answe your question...yes you can use the stock pulley. Not much use in balancing the pulley or the damper (damper is already neutal balanced). """"
I lean toward the billet because I've had 2 stock ones break so far. Though I made the mistake of using a used bolt when I did the replacement. It looks like the bolt broke first then without support the balancer twisted apart. I think the billet one would be strong enough to hold for a while even with a broken bolt. If I am incorrect let me know. I want to try the Mustang bolt as I've heard they hold up better(what was that part number...).
Also I understand the BHJ needs to be honed to fit the crank. Is this something I can do with a drill mounted hone? The crank is still in the car and I would have to mic it in place and hope my measurements were correct if I take it to a machinist. Will my timing vanes bolt up OK to the BHJ? Is timing an issue?
Any info would be appreciated.
Thanks
