Don't worry about torque. Here's a way to coax more speed out of it:I tried to find out about the NP200 transfer case.
"Most everybody who has posted is right though. The 200 was built for engines that had no more than 130 hp in trucks that had 7,500 max weight ratings with an expected top speed of around 45."
"The NP200 is installed as a passenger's side drop in the M715 / M725 military Jeeps, exclusively with the T98 four-speed transmission. The NP200 was found in other military vehicles, such as the M37 beginning in 1946."
Sounds ideal for Seeker (did Doug check max torque specs? He did not because Doug)
