I'm not saying a 340 cam is bad probably would even be a decent choice for this engine, but as performance cams go it rather small more in the RV range

Absolutely. That is where 90% or more of people who build their own engines make their fatal mistake. Too big a cam.

Cams are like carburetors. If you err on the small side, you will be happier every. single. time.
