Re: 6223 Crankshaft
Not true a 6223 will balance without mallory in a 427 , the only 6223 I have seen that had to have mallory was previously balanced for aluminum rods , I've built 3 in the last year using the nos 6223 on ebay , 2 had to have counterweights cut for piston clearance , not uncommon with factory style pistons
