Lets talk pulley

I am happy to say new ATI pulley is in.

Had to make a crankshaft-to-tool adapter to fit our M16x1.5 crank pulley bolt threads.

Used the Proform 66514 pulley install/removal tool. However, had to remove the electric fans for more clearance. Otherwise worked as described. https://www.proformparts.com/product...ol-fits-all-gm

Did NOT have to clearance the ATI pulley hub. ATI told me, I should have about 0.0001" clearance. I measured around 0.0004" maybe less.

With some Anti-seize on hub ID, the pulley pressed on smoothly and evenly without effort. I even got the 90 degree final torque as well.
