Agree with others a little much for cam, also what are you running on the exhaust side to make it breathe better? And I bet you need more stall in the trans too. It should run at least 15s or high 14s with that car.
My dad had a 70 satalite and we got it to run a best 14.88 at 91mph with a 318, had a mopar 260 cam a two plane edlebrock intake, and a 600 holley tweaked. He only had 3.55 gears on h50 15s as I recall.
