I really all depends on the timing set used in the build. The crank gear varies in thickness from timing set to timing set. The instructions assume you are working with a stock motor as well. My final measurement required me to space out my accessory bracket more than .100 to get my accessories to line up with the crank hub. I also could of had the hub machined down, but that would have thrown my supercharger crank pulley out of alignment so I opted to space out the accessories.

OP, I'm in the middle of putting my ATI damper on and realized a OEM style bolt does not tighten down against the TH ATI style hub...

The OEM hubs have a small through hole for the 7/16-20 crank bolt with a shoulder for the head of the bolt to sit against. The TH hub does not have this feature so you only rely on the press fit of the hub on the crank.

This doesn't seem right.
