Just an FYI- - - -the "small cap" setup requires a LOT of machine work to adapt it to a stovebolt engine, plus a gear swap. I've done one of them, just to see if I could duplicate the Langdon conversion, and I don't plan on doing any more. It's less work, and much more original-looking to put HEI parts into an original stovebolt distributor housing.
