While Im only using the short block from Blueprint, with my own selection of parts, mild cam etc, my approx hp is somewhere close to 390-400, Im using a Turbo Action 10" 17805ST (tight) which is listed as a 3500 stall. In 3rd gear on the brake and matted I see about 3200, it works great on the street, and strip, but I want closer to 4000, I'm changing things in the motor slightly this coming winter and plan on a 9.5" 3800/4200 stall likely from Ultimate, supposed to still drive nicely on the street. I'd suggest dont under stall, just call! (a converter company!)
