Well, I can't go to the 2.100 rod bearing for a stroke increase. Not for the full .275 increase anyway. It would move the rod bearing oul holes too far and thin the inside of the crank throw. So i decided to go with a 2.20 bearing and 4.315 stroke instead. Not quite what i wanted but thats life. It will be interesting to see what these changes will do for power. The cubes will be 550.5.
