Thats thru in theory, but in reality it need moore. I don't think a 110 GPH fuel pump is big enough.
Fuel pump must struggle against fuel filter(s), regulator, various bends and turns in the fuel system and G-force when you floor it.
what you have described is supply issues. You (and others) have made assumptions on where the engine is going and it's location relative to the fuel tank. The OP stated none of these.
I have data (meaning I have tested) showing a mechanical fuel pump supporting 837HP with no issues.
