You can still possibly offset grind the crank to 2.200 bearing, 4.270 stroke, use the common 6.7 long 2.200 bearing x .990 pin rods. Rod availability is now good, bearings are a touch cheaper, and you have fourteen more cubes. You could possibly go to 4.25 stroke and use custom gaskets to make up the .010 minus deck height, if you want a common combo.
