Gears multiply torque by the gear ratio.........
So 180 * 4 (1st) * 2.57 (low) * 4.7 (crawl) * 4.1 (diff) = 35657
Change for what ever your gear ratios are.
Every gear is only about 98% (except 4th which is 100%) so you need a correction of .98 *.98 *.98 * .98 =.92
or .92 * 35657 = 32804ftlb at WOT 3000 rpm engine.
less throttle would be less torque.
