I'm in the process of piecing together parts for a big block stroker motor (496).

I have a Scat 4340 forged internally balance crank (will be using 6.385" rods) and I need to know which ATI damper to purchase. Part number? Size?

Thanks in advance. :)

You will probably have to have it honed to fit. Check it.

Thanks Mike. :)

Thats the one I have and yes, it needed to be honed.
