Interesting Massey Repower with 13hp motor.

I don't know, that motor has no torque output which is one thing those old tractors had going for them. It's also scary light in the front end.

oh i dont disagree with you, I would ideally like to find an old wisconsin or a onan,

Well, if you had a Wisconsin, you could build one of these,

OEM was 40hp at 1500 rpm or 140 ft-lbs. The replacement is probably 13 hp @3750, that is 18 ft-lbs...what do you think the chain reduction is? 7.7:1 would be needed for equal torque.
