NOTE: For those using this for search info, the Egge 343 pistons are listed on their site under Rambler, and are slightly shorter than listed. These will provide CR over 10, but quench isn't perfect, read for details.

I tried install my pistons into my block today. The bore is fine, and the rings fit. The counterweights on the 360 crank contact the piston skirts at the bottom of the stroke. What do I do now?

I'm thinking the easiest would be to have the counterweights taken down, then rebalanced, but I don't know if you can do that. One suggestion was to machine the pistons, but that sounds like it would take more effort and money.
