There are many new series type 34 motors that are more powerfull than the original Bridgport ones with less inertia to boot.
Bridgeport originally fitted anything from 950 ozin up to 1100 oz/in in the 42 frame.
I have seen some triple stack 1700 oz/in motors in a 34 frame advertised.

What makes you think that one of these will not work ?

My Beaver mill which is bigger than a Bridgeport runs 950 oz/in motors direct onto a 5tpi ballscrew with no problem.
