Please, in need of quick response ASP pulley I.D.? My ASP pulley has a stepped I.D.. About 5/8" long I.D. is a loose fit on the crank shaft & 3/4" long I.D. remains for the interference fit onto the crank shaft. The stock pulley had no step in the I.D. (was same diameter through the length of the bore). Entire length of the stock pulley was machined for an interference or at least metal to metal fit. Does your ASP pulley have a stepped I.D.?
Need to know before it's mounted. Thank-you in advance.

ASP has confirmed that the step in the bore (loose fit in the I.D.) is done to allow installation with the factory crank bolt. Basically, the pulley engages the crank shaft about 5/8" before the crank bolt is needed to push it on.
I heated the smaller bore (I.D.) in the pulley until it sweated & then used the old crank bolt to push it all the way on. Once on, the old crank bolt was removed & a new crank bolt was installed & torqued to spec.. Posted the findings for those needing future information.
