I have a camaro with 396 procharged making 650rwhp with stock damper and it,s keyed,running 14 lbs boost.The crank is externaly balanced,it,s runs good but i thing a better balancer should be instaled to help the the crank to last longer.I,am thinking the ati damper would be a good choice,what would i have to do to install the procharger crank pulley on the ati damper,does,t it have to be shimed or anything.The procharger is a disc with 2" belt.
Any advice would be appreciated from you guys.

The crank pulley spacer will need to be milled down a little bit.
