I am not a cam guru, but with that cam you are looking at .720 rocker arm lift. I am guessing the duration is at 50. I ran a cam very similar to yours in my 434 in our Super Street Nova and it worked great the car was 2850 pounds and ran a best of 9.44 @ 143 mph with 4.86 gearing...

I hope this is helpful...

You will want about 6000 stall, turn it 7500ish and should run very low 9's at least, maybe some high 8's. Cam should be fine if you have the springs and pushrods to handle it.
