Thoughts on a 225 rebuild

The high rod ratio of the 198 rods with a 198 crank can be a bit misleading; most of that high number comes from the short crank stroke, not the 5% increase in rod length. When the 198 rods are used with the 225 crank, then you only get the 5%; not all that much of a change. Using the 2.2 pistons may be an advantage in getting the piston top closer to the top of the bore, doing the quench thing, etc.
