Yes, you need to install a rear motor mount on the close-coupled engine and drill new holes in the stringers along with a few other changes.

Yes, I swapped my NXT transmissions for Huber 1450s. According to the Mercury Racing shop manual the NXT transmissions are rated for 800 ft lbs of torque.

I guess you would recommend doing that before doing the upgrades?
What kind of torque does the whipple 700 upgrade give you?
