Nice find, I love my old Unisaw.
This would be my first stop for the correct motor.

Yep, just checking if anyone here as or knows of one.

Once you have the motor frame size, the rest should be easy.
@BigMike782 can you post a pic of your motor nameplate for OP so he can get the frame info?

The Unisaw motors are special beasts because of the proprietary mounting tabs on the motor case.
Keep your eye open for dud electric pressure washers like the one pictured. I have seen these for as little as $50 when the pump goes bad. They usually have a 1 1/2 HP motor. That special mount could be fabricated and strapped on to the motor with metal (pallet) banding. Have also seen table saws going for $25 with 1 HP motors.

Uni saw motors are unique , they are not standard frame sizes
There has been discussion on adapting frame 56 motors to a Unisaw on here in the past. a little bit of ingenuity & fab skills can make it work .

Leeson makes motors with tabs for Unisaw mounting. Please, if your saw cabinet has the rounded hole like in the picture I posted above, do not hack up the cabinet to cobble a 56 frame motor into it.
If it were my saw, I would find an original RI motor and have it rebuilt before I adapted one. The old motors run very well.

Found a motor. 1 hp at 1725-and weighs as much as a Cadillac.
not sure you'll be happy with that. I know I wouldn't be

I have a spare 3 ph motor but not the single phase
I found various hp Leeson Unisaw motors available. Up to 4 hp quickly scanning. Some were pricey! Up to $1000.
Zoro had a 2hp version for $700. Zoro has 20% off coupons available once you make the mailing list. They could have additional hp available.
I did see a SF of only 1.0, where in this application, I would expect 1.15.
One website stated not knowing if the fit was for left or right tilt saws. That was for you to determine.
Agreed. Wrong RPM unless he gets the matching 5.5" diameter pulley, and too little power for modern carbide blades.

I did get the original pulley with the motor and should do just fine as I don't plan on cutting anything over 2"-maaaybe 2 1/4'-maybe. If I need anything thicker then I have my tilty which has a beefier motor.

Yeah I will have to cut some 2" oak for the sub-rails on my car. But that is 2 long pieces and that will be it. Otherwise it will be short small cuts ash. So nothing super heavy for long periods of time.
