i am really sorry for putting it in the wrong section! I will repost in tranny tech.

 

Since it's still here, and since I found it here, here's my take:
If you're gonna run a dual plane, and drive it every day, try a stall about 500 rpm over stock, like B&M's Holeshot 2000. If you wanna get wild, a 2400-2500 wouls do. Using a 2800 or higher is wasting all that this stroker has to offer.
