well, for a measuring stick, my 318 Duster has 2.76 gears, stock exhaust manifolds, stock converter, summit cam and I home ported the stock 318 smog heads. I have a 770 holley on top. Short block was never apart and it's a '76 motor. It runs 14's at 94 mph, with a 2.2 60 ft. Pretty similar build as yours, except you have better gears, and if you have headers, that's another plus for you. In other words, you should beat me every day of the week and twice on Sundays. That is why I suggested "tuning what you have" before throwing parts at it.
