FWIW, I agree with Bill.

Another thought, perhaps you could de-tune the MGB motor to limit its torque
to roughly that of the original motor.  If you keep the original rear axle,
I think your chance of avoiding permanent changes goes up substantially plus
the work involved goes down.

But it does seem to make more sense to me to commence with rebuilding the
original rather than trying to install a 'temporary' substitute.  Engine
swaps always turn out a lot more complicated than they look.
