My estimate was weighted more to my recommendation, with your setup.
350 rwhp would take 420-430ish hp at the crank, and without a mechanical fan attached to the accessory drive, and the fact that you have headers, and 2.02's, I estimated high, because a 4150 750 Double Pumper is a very capable carb especially at your mod level....a 3310 VS 750 is going to be holding you back...Maybe 320rwhp if you can tune it in.

Good luck.
