I'm one of the stupid, i guess, for running a 9.6" deck R3. With a 4" stroke and 6.2" rods, it keeps my R/S angle very reasonable while having 422 cubes. Could do it with a low deck, but why side load the crap out of the cylinders with a horrible R/S angle when you don't have too. Maybe this is why other manufactures make tall deck block versions....hmmmm.
