If it is a 1973 model, there was only one engine- the 399cc opposed twin which was made by OMC. There was two versions of this engine-a 21 hp and a high performance 30 hp. You could tell the difference between the two engines easily. The 30 hp engine had dual exhaust(2 mufflers) and also ran on premium gas only.

The Allstate 400 at the Brickyard was on July 26, 2009. It was won by Jimmie Johnson.
I reckon about £400-£500 if in decent condition
75 to 400 dollars depending on condition.
Bascially they are the same engine.
Yes you can drive a snowmobile in Canada with your G1 as long as you are insured, you can not drive on the 400 highway but who would anyway with a snowmobile, but you can ride the OFSC Trails as long as you have a trail permit and sticker as well as plate and insurance.
Should run 60 to 70 mph.

A motor will operate on 400 volts.
A typical Skidoo snowmobile can weigh around 400-600 pounds, depending on the model and specific features.
