Would this motor have a good crank for pulling.
It was an irragation engine.

3750 engine has the counterbalanced crankshaft if that's what you're looking for. All counterbalanced crankshafts use a fluid/viscous crank pulley type damper, not a rubber pulley damper. So, they are easy to identify by simply looking at the damper, without tearing the engine apart to verify.

Would depend on HP and RPM you're running. In the days of old,there were plenty of HOT pullers before  the counter weighted crank appeared. Just sayin
