Comp cam xe274h power brake issue???

I've run 230 degree cams with 9.5to1 compression before. Had about 11" of vacuum and wasn't a problem for the type driving i did, mainly light cruising and some strip passes. Didn't like repeated hits on the pedal as it would get a little firm. If you try it out and have any issues you can always add a vac. storage canister.
