I'm putting one of the new Scat 4.25" cranks in a '64 LR block now and I'm using the 6.700" rods just to keep the pin out of the oil ring groove. The rod ratio for the 6.700" rods is 1.58 versus 1.60 for the 6.800" rods. Not much difference at all. The 6.700 rod allows me to run a conservative 1.34" pin height.
