The crankshaft began life in a 330-inch Olds, but went through some changes before ending up at the Jeg's Engine Master Challenge. What a life it's led! The chromed-and-coated piece was machined to a stroke of 3.385-inches. Many feel the 330 steel cranks are too rare, but Dick always seems to have a few on hand. He's also got SFI-certified flywheels drilled in 330 and 425 Olds bolt patterns.
