Default Which ATI Balancer Part Number?

http://www.atiracing.com/products/da...s/damchevy.htm

Looking at the chart I'm not sure what balancer to use for a nitrous 408 application.

I sent an email to ATI tech support for them to recommend a balancer for my application. I'm building a max effort n/a setup so you may want to contact them but I have a feeling they would probably recommend the same thing for you. Here is what they sent me. Beware its not cheap but well worth it for the money for peace of mind.

This is from John Lane: jlane@atiracining.com

I would use the oem size of 7.5” for the added protection you will need on the street. And the part number for the f body drive is 917242.

That one has the AC pulley which I don't need. Guess I should have mentioned that in my original post. Thanks anyway.
