I was spec'd one close to the first 2 from Geoff@EPS. He gave me a 240/251 636/621 on a 114 for my 416 L92 headed motor. It was spec'd for a pump gas 11.3:1 motor with a car that is 3425 w/o driver and a ~300 shot of nitrous.
Hope that helps you.

Stick with what ya got. Is it worth a cam swap for another 10-15 hp

Would be worth it if it makes 10-15hp and 20-25 ft lbs across the board

IMO they wont pick up more torque until higher in the RPM band..

I would keep what you have also, personally dont think there would be much gain. If you have the money though, there is nothing wrong with trying something different if you really want the extra tenth or 2.

IMO the second cam would make the most difference but as stated maybe
only a 12-15 horse improvement.
