Yes, the torque spec for the stock engine mount bolts on the Gen 3 is also 35 ft-lbs also. I misspoke (mistyped?) and meant to say that "35 would probably be fine".The bin-o-facts lists 35 ft-lbs for the slider bolts! Granted that section of engine bolt torque is still orange but surely the values have not changed from the Gen 2's?
I do not know exactly why SW Motech said to go with the higher torque value, but I'm sure there was a reason related to them being sliders and not just holding the engine up. Either way, they tightened up to 55 ft-lbs with no difficulty.
