I had the pleasure of working with a couple of friends on the restoration of a running example of a 1938 Model 177 6 cylinder Hall-Scott from a logging truck. It has been set up as a running display engine. It has 855.3 cubic inches. 5 1/2 " bore x 6" stroke. It runs at max 1800 rpm. This runs approx. 245 H.P. The pix on flickr

are from when we gave it a cosmetic uplift and I spent about 6 hours polishing the aluminum valve cover. There is a web site that shows more info.
