Here are a few examples of tractor engines with equal sized power ratings in gas and diesel with different sized engines - and also two equal sized in gas and diesel:
Deere 2010 (and 1010 with diesel version) Note that both 145 engines are equal bore and stroke, and the gas has more torque)
145 gas: 39 horse, 114 lbs. torque @ 1500 RPM 145 diesel: 36 horse, 95 lbs. torque @ 1500 RPM 165 diesel: 46 horse, 119 lbs. torque @ 1500 RPM Those are specs published by Waukesha. The gas 426 runs 6.2 to 1 compressoin ratio. Diesel runs 17.5 to 1. Horsepower is stated as "rated horsepower" and torque as "maxium torque - RPM." So the 426 diesel runs a max torque of 259 lb. ft. at 1600 RPM. Gas 426 264 lb. ft. @ 1200 RPM

707 cubic inch gasoline Mack had 5" bore by 6" stroke. 232 horse @ 2100 RPM and 617 lbs. of torque @ 1200 RPM.
