Dyno #'s

Anyone have torque/hp numbers at various rpm for stock 74 or 80 btsv?

Go to advanced search and search "dyno charts" within topic titles only. You'll find a topic on that issue. Stock 74" U-model bikes put about 30hp rear wheel. Paul Friebus, at American Cycle Fabrication, does a lot of work on flatheads, and also dyno tests. He may help you on torque curve specs.
