Considering that our beloved AMC's share lifters with our MoPar bretheren, there HAS to be SOME way to utilize the hydraulic roller lifters they have had the benefit of for many years now. Have you looked into the feasability of making guides ( "dogbones" some call them ) that are for AMC lifter bore spacing that fit the Chrysler hydraulic lifters ? Once these would be available, it would be a simple matter to order a cam to use them. God knows I'd buy more than one set ! How about it MC ?
