Connecting Rod Mystery

i have a set of 340 rods, casting number 3418645, they are bushed with floating wrist pins. they do not have any oiling holes drilled into the pin end. i did buy a set of direct connection rods new 15 years ago. i do not recall the casting number or part number. they came with hi strength rod bolts, polished beams, bushed for floating pins, & were drilled on both sides of the pin for oiling. they did have a logo cast into them, DCP, which i assumed was for Direct Connection Parts. however i have seen this same logo on stock 360 rods with pressed pins. the one thing about the world of mopar, never say never, any thing is possible. when you have the smallest budget of the big three, if you can use one casting number in several applications with slight machining, then Chrysler would have not been above doing it!
