I agree that it sounds like a used Kirkham would be the way for you to go. As far as the engine I wouldnt shy away from an iron block/aluminum heads if you want to be more modern and save some weight. I'm pretty sure the AL blocks are limited to hyd lifters because of expansion, so that is something to consider. Lets hope AT Francis/ Bluethunder can produce his iron block some day soon. He did some major re-engineering on the oiling system and it sounds like it will be a "killer" block if/when it makes it to market. The last I spoke to him there was absolutely no ETA.
