So I put the puller on the dampner and moved it back to where the alternator lines up with the crank pulley and the aftermarket Hemi water pump pulley is not even close. It looks like the pulley I need would just about hit the water pump bolts like on a 383/440. I do have another supposed Hemi crank pulley that is smaller in diameter and shorter than the one I have on the car which I was told was the right pulley. So, what is the diameter and height of the correct Super Stock Hemi crank pulley and water pump pulley? I will ask over at Class Racer and see what they say.
