I know there are differences between dynos, so the following shouldn't be
taken as gospel, but...
A couple of weekends ago NWDE did a dyno day for it's members. Guy Selle ran
his vintage racer 2000 that has Mikunis, a B cam and slightly bumped
compression. Other than that, it's very stock, right down to the factory
exhaust manifold. He wound up pulling 135 rwhp. I'll try to get the rest of
the info from him (what rpm, how much torque, etc.).
