My 434 in S/St trim 2830 lbs runs 10.90@149-151 depending on the air. Motor turns 7600 with 14.5x 32 and 4.57 gear. Motor makes 830@7400 w/ 676 ft/lbs torque @ 5800. When I first built this motor I ran 4.86 gear and 8" convertor in S/G trim (2600lbs) and went thru @ 8000. I now use 9" conv with the 4.57 gear.
