How much would be left on the table?

Thats the first thing I thought when I saw the lsa, man, this is gonna sound awesome! I bought it with dyno time only, it was in a 340 with w2 heads, and a restricted carb for circle track, and it made a little over 500hp. I figured with 80 more cubes, 2.081.65 valves, unrestricted intake/carb, I may be able to best that without having to rev much past 62-6300. I guess I am beginning to get greedy for power though lol.
