they have the same base engine. The 3520 gets a turbo, while the 3720 has stepped up fuel delivery, turbo, and an intercooler.
Note that all the current engines are slightly de-tuned from the previous series. The 3120 has the replacement engine from the 4310, yet it is slightly less powerful. the 3320 engine is more in line with the 4310, but it is the 4410 engine replacement.
Don't worry, Garrabo, if the 3120 work for you - great! it is a fine machine!
