Shellehamer front suspension kit

If you use the math formulas to determine carb size, my engine should use a 750. However, I tried a 850 DP season before last and it didn't like it at all. So the dominator went back on and has been on since. My 360 stroker (383 if you believe the math) is pushing almost 14:1 compression and has a fairly big cam (Comp Cams roller, .654 intake, .655 exhaust, duration @ .050 269 intake, 276 exhaust) and I use 113 fuel with W2 ported heads. It's just what it likes.
Curious what that combo dynoed at? Or your best guess estimate.....sounds like a lot of carb.
