Dyno 2000, How does this sound for my setup?
Here is the screen shot of my setup with the new heads. Does this sound right? Any suggestions to get a some more HP out of it? A 700cfm carb gives me a few more HP.

Looks like Vortecs will be better, or should I just suffer a little now, in order to have it better later on, if I replace the cam?

Thats why desktop dyno shouldn't be taken too seriously.

Yes, that was with the stock Goodwrench heads, I'm still working the bugs out, obviously I should be running faster than that.

I believe they make a marine line of XE cams, however, that have a 112 LSA.

not bad mark, set up the vortecs with smaller valves, as the flow numbers are for the smaller valves. I found numbers on my 487 heads, and for me at least it seemed more cost effective to get a supercharger for max power.
I still think you have a major tuning issue myself. I have personally blown the doors off of mid 15 second cars and I have 1971 truck heads. I have the XE262 too. Can't you get different metering rods for the edelbrock carb? I know playing with that stuff on my quadrajet really made a difference.
