So we all know there are some pretty good power numbers coming out of these mod motors, but the parts used and the mods made to cases/cylinders are a little in the dark. I know the 700CFI crank can be used in the 600 HO, with 700 cylinders, as long as the cases are properly clearanced, but what else goes into making this motor work correctly?
And on that subject, let's discuss the other possible options..
600ho - 64 mm stroke
700cfi - 68 mm stroke
800cfi -70 mm stroke
600r-70mm stroke
800cfi crank in 600ho case appears to be what the Carl's 860 is based off. But they are using custom cast cylinders. It makes me wonder if there is a OEM piston and cylinder combo that could be modified to work? Maybe using a deck plate and some port timing changes?
I have a spare 700cfi crank and 600ho case, I am thinking about finding a 600r or 800CFI crank and really trying to figure out what possibilities are out there .
