Gene; I have three big block chvys apart right now and there is nothing
in any of them that fits your description. Did you get this motor from a
engine builder ? It could be the camshaft drive pin from a ford fe
motor. It sure fits the size. There are no .310 solid pins in a
chevy. Doug Odom in big ditch
