Critique/suggestions on 273 engine build

I was looking through the glovebox on my 67 fish with a 273, performer, 600 eddie, and found a really neat goody! There was a cam card and a receipt for a custom ground cam from a guy named Roy Chambers. He owned RC Automotive Machine Shop here in Alexandria, Va. just 10 minutes south of DC. For $65 he ground a cam that he labeled the Brute Force that had a duration of 280* and really not much lift ( I think it was .449/.451). Found two big ol' Brute Force by RC stickers also. I really haven't driven the car at all because I've got the seats over at the upholstrey shop. Can't wait to see how it runs!
