I own a 350U it has far more displacement, and is substantially more gutsy. It is heavier, and will pull 3-14s in heavy soil. The back 1/2 is the same, but they are different animals. Jim
 
The 330 has a 135 cu engine derived from the C engine family. The 350 has a175 cu engine derived from the H. According to Tractor Data the 330 weighs about 4100 lbs, the 350 is 500 to 600 lbs heavier. I would say most weigh more as they have fluid in the tires. Also the 350 is 2 inches longer at 75 inches. The basic difference is the engine.
 
For sure you can tell a performance difference. If there wasn't a performance difference they wouldn't have the different model.

The C135 in the 330 is a punched-out Super C engine put in a tractor that's the weight of a 350. So in some applications it will feel underpowered for its size. It was IH's entry into using RPM to make HP instead of displacement, and the results weren't spectacular. On the other hand it was far from a disaster too, just "meh."

It was also IH's first attempt at building a lightweight utility tractor to compete with Ford. Prior to this the 300/350U was it, but the tractor was much larger and heavier and more powerful than an N series and what came after. Again, the results were not stellar, but far from a disaster. Just "meh."
 
The 330 is essentially a 340 engine bolted to a 350 rear end. When the 340 tractors were released, the 330 was dropped.
