Stock fuel pump limits

What are the limits of a stock 340 fuel pump? Trying to decide if upgrading pumps will be necessary for the occasional trip to the drag strip.

Combo is as follow: stock stroke .030" over 9.7:1 340, RHS heads, 231*/.562" hyd flat camshaft, airgap intake, Dougs headers, 727, 3.91s.

I've got a 670 Holley Street Avenger carb on it now, but I'll soon be swapping in a 750DP Holley and taking it out to the drag strip. Just wondering if the stock fuel pump will suffice. What do you guys think?
