Tom, see NH dyno's
http://www.bonnevilleamerica.com/forums/...e=0&fpart=4down the page a bit they made up a spread sheet thing listing mods and what their dynos were. Pat was one of the only ones with the big bore but if you had more time you might read thru the pages and see who else had what for torque and hp. With the BB, Pat's torque was at 55 and he had 36mm mikunis for carbs.
