300hp.
you put a 650 cam in because its cheap. Cheap people are not going to spend the money on a dyno run to find out they gained 2hp. Its more power for cheap, end of story. You want performance, get a real cam and higher compression big bore pistons.

Im not hating on the 650 cam, I have one on my shelf for my next build but for my current build i went the HyPo stuff. The best place that i know of to get it is http://www.dynoman.net/. I bought pistons, cam, gaskets, e-ignition....he has what ever you need.

don't know what the 650 cam on it's own will do, but the 650 has a very lively engine, but that would include the head as well.

 That's why I'm swapping an '82 CB650 engine into my '71 CB500. :)

 I'll let you know soon. Still gathering parts. The motor mounts are all the same. Some wiring differences. I'll be doing a thread when I start the swap.
