why would you guess less? the shorter stroke would probably mean the crank pins overlap more in a 2.8 crank than the 3.1, adding to crank strength. and the greater compression distance of the 2.8 piston vs. the 3.1 would leave more metal in the critical area. i'm willing to bet a 2.8 can hold up to whatever the 3.1 can, if not a little more.
