Hi Bill,

Ultimately, a Powerglide coupled with any available rear end gear will have
more overall torque to the wheels than a 4spd with the same rear end
gearing.  That's because of the gear ratio of the PG 1st gear added to the
torque multiplication of the torque converter.  That however doesn't mean
that it will do it quickly!  It will actually out pull a Std transmission
FC.  I agree with Bob's conclusion.

The 95hp engine coupled with the 3.55 rear gearing is a favorite among
UltraVaner's and was one of the most common drivetrain configuration offered
by Ultra Inc. and most of those haul considerably more weight. 

Shouldn't be a problem,  a little slower.
