Welcome to the board.

Lots of info in "search" but the ATI damper is probably the most commonly used, even though it's a little pricey. That's what I'm using. Make sure to pin it to the crank, you need the ATI pin kit.

You need to use the ATI balancer, as the ProCharger 8 rib crank pulley is designed to work with it. Bob

ok cool ill get it then, the only other question i have right now is how do i get a spring loaded tensioner i have the d1sc and the j bracket but no tensioner

SDCE sells the spring loaded tensioner. You have to send them your J bracket for them to modify it. Bob

^^Yep & its not cheap either. But there are other alternatives. Do a little searching in this section & you'll find several threads on different methods to eliminate belt slip & thorwing.

I have the ATI super damper crank pully and the SDCE spring on the J bracket and don't have and belt problems.

If you are building a 408 you might as well have the crank keyed instead of simply pinning it for the ATI balancer. A key is going to be much stronger than a pin and the balancer is already slotted for it.

A spring tensioner system of some type is definitely better than the standard Procharger J bracket as belts stretch as the RPM increases. Without a tensioner to take up the slack you will likely end up with slipping problems over time.
