318 block and I don't know

I remember a thread here years ago about how to do it. About all it does is make the motor a little more torquey because of the longer arm on the crank. Supposedly, you use some Silvolite pistons with a 1.741 compression height, and mill .065 of the tops of the pistons, and then mill the skirts to clear the counterweights. I was talking to my machinist about it one day, and he said it would be easier to turn the counterweights down and neutral balance the motor than fool with the piston skirts. It would be ok for a stockish type build if you wanted a little more torque, but it's a lot of work just to say you did it! There's easier ways to make torque...lol.
