cam shaft selection
We had that cam years ago in a basic stock 318 70 Satalite with only a 2.71 ring and it was OK, upper rpm better, not much loss in the low end, ible was good not much more than a stock cam.
With that cam I recall the vacuam at an idle was about 3 psi less, brakes were still fine and you may find you need the reject the carb etc. But the questions above are what need to be asked and resolved.
Purpose of use, other mods, gears in car etc...
