My Hudson has a flathead six. a few years ago I had it on a chassis dyno, and we made a couple of high gear runs. It made 186hp at 4200rpm and max tq was 275 at 2700rpm. The torque was over 225 from 1800 to 4600... thats the range we did the pulls in. If I ever get the head gasket to seal properly, I'll give it another shot.
