I just got an email that says I need to cut my 440 crankshaft counterweights down to 7.25" to clear the block. I know that many people have built the 400/451 combo. So what did you cut the crankshaft down to? Besides cutting some room on the block for rod bolts, were there any other block modification that were needed to install a 440 crank in a 383/400?
