I picked up 01 bullitt, and was wondering if this was a stock crank pully, it didn't look stock to me, but previous owner said it was.

Sorry, I'm not familiar enough with the mod motor stuff. I'd ask this in the Tech section specific to your year Mustang. Many more members in that section. Good luck

no thats not stock, looks like part of an under drive pulley set, not sure about the trigger wheel on the front, is the crank sensor mounted externally? if so its much different than stock

Thanks for the response orange and jwog,
The rest of the pulleys look stock, the cam sensor looks to be mounted on the outside of the crank pulley, I can't see any names on it, I didn't think it was a stock pulley,

the rest of the pulleys are part of an under drive set, the wp and alt pulleys are larger in diameter, the crank is smaller in diameter than stock. this is to help reduce accessory drive power loss. not sure why they ran an external trigger, but i suspect that it was for some sort of stand alone fuel management? maybe somebody else knows for sure
