Thanks for the responses. One can never have enough opinions to toss around. My biggest issue with the liners is the deep pitting around the outside. I Know these are almost 1/4 inch thick but the pitting is really deep and I would hate to put all the time replacing rings and a valve job only to find a hole in a liner a few years down the road. The bore measures 3.887 . Should be 3.875. I'm sure it would run ok with a new set of rings and a valve job, I have done that many times before. Depending what I find on this project I will probably do it again. I am planning on checking with some custom sleeve builders this week just to satisfy my couriosity, And I am going to check the demensions on the liner from a model c case, I don't think they are too far apart in size and you can still get them new. If I can could get them to fit with a minimal amount of machining that could be another option, Hope everyone has a happy new year and pleny of time to play with some old iron. Thanks, Todd S
