a stock 3.0 for example is 150 hp at 3000 rpm and 180 ft lb of tourqe. how would i figure out what the tourqe is say in 4-lo with a transfer case having 2.57 gear ratio, or even better dual cases with 4.7s in the rear case. i know how to calculate crawl ratio but was curious if its possible to do the same with tourque?? Thanks
