I may be wrong but I suspect the 58mm throttle body might be hurting your torque.

I think the 58mm throttle body is hurting the torque, switched back to the stock 50mm after cleaning up the runners and polishing and smoothing out the whole inside, and it feels alot stronger down low..

I had the S&S 585's in a previous build and loved them, great from midrange through to top end, they loved to rev. Should be ok at 10.5:1 comp too
