im not going to do that but how do you know where to put the holes in the crank?
Forget that crap... SB mopars have been turning HIGH rpms for YEARS with normal cranks.. the most I ever did on the crank was elongate the oil hole some.. you can do that with a file or have the crank grinder do it (they know what I'm saying on that).. but its just the slot across the oil hole.. as I said before.. I have been 9600 rpm and its still together.. and I sure dont do anything magic
