I picked up a July 2008 issue of "Hot Rod Deluxe" off the magazine rack the other day. It seems to be a magazine geared towards retro and old rods. I think it would be an issue most Stovebolter's would enjoy.
Inside it is a great rebuild article on the Blue Flame 235 cu in engine.
It claims that this rebuild gives the following:
Peak torque Arpm: 217.0 lb-ft @ 2400
Peak Power @ rpm: 132.1 hp @ 4000
Average torque: 198.4 lb-ft
Average power: 111.9 hp
