Jim, If it is just a stock rebuild and $ are a concern, I would go with the Badger over the Keith Black. If I recall correctly, the Keith Black pistons for AMC run a .930 floating pin which means you have to bush your rods. This can cost about $200 for the parts and labor. Add that to the cost of the pistons and you are better off buying a set of pressed pin forged pistons. Not worth the extra $ for a piston that is only slightly better than a cast Badger piston. I have Ross forged pistons for AMC that will cost about the same as the Keith Black pistons by the time you are done bushing your rods and they are a much higher quality piston. I responded to Kenneth on this as well.

A: I'm going to cc this to the AMC-list and some other AMC suppliers I know and find out who's who now on those pistons. Lots of suppliers over there with different choices. From: "Kenneth Smith" caionnea@xxxxxxxxxxxxx Subject: Re: Re: 401 Overbore I'm interested in replies to the response cited below. A shop in Denver, CO recommended Badger pistons as a *second choice* behind Keith Black hypereutectic pistons dished out to the target compression ration. Kenneth
