From at least '46 to '53 the cranks are interchangable on the "small" sixs. (218/230 ci) The P15 is a 218 ci from a '46-48 Plymouth passenger car. Basically the blocks for '46-'53 Plymouth, Dodge and Dodge truck dirctly interchange and you can move cranks/rods around no prob. Only gothca is the flywheels. The 230 uses a 8 bolt crank hub, 218 is a 4 bolt. Hole spacing is identical however but the crank hub length is different betwen the two requiring different flywheels.
