>Hey Marc ,
I just got off the phone with both Callies and ATI (balancers) , and both companies said that the tolerances were machined for O.E.M. crankshaft size . So that leaves me to believe that it's the S/C crank pulles that are going to have to be trimmed down !?! Can you tell me where you got yours done , and I "assume" they did a great job ?

The ATI balancer will fit on a Callies crank and allign up just like stock for the stock serpentine belt but it's the face of the ATI damper that stick out (if it was on the motor it would stick out towards the radiator) and the face of the stock damper is recessed (towards the block).

I machined the Pro Charger crank spacer to fit the new balancer but it looks like it's going to get machined again to fit my new crank trigger sensor...

I think I got some pictures on a disc at home, will take a look and post later.

>Can you tell me the number of the machine shop that did it for you ... that will probably be easier than having to explain to a shop that never did this .
