Guys, his engine isn't stock. It has headers, an intake and a carburetor. That's not stock. The headers will lean an engine out a bit. The 600 carburetor fattens it right back up. The intake can only be helpin. The little motor probably runs pretty good. No, the factory never rated power at the rear wheels, but that's what he asked. He didn't ask for cam recommendations or anything else. He simply asked for an estimate based on what he has now.
