Which engine puts out the most HP? I have a C-85 that I was going to put the 0-200 crank in, but now have a chance at a C-90. Looking back at my old Cub Clues that compared the range of engines you can put on a Cub, it looked like the C-90 is the best choice, but it didn't have the 85 stroker listed for comparison. They may be so close it doesn't matter.
