Can you use a mechanical fuel pump with Magnum front cover?

I've converted my 318 Magnum to carb, put it in a '65 Valiant, running an electric fuel pump low psi, no regulator needed, they sell em on summit, believe it was MSD brand, seemed like around $40. But note, you MUST mount it about 10 vertical inches away from the fuel tank so it won't burn up, too much work for it to pull the fuel up in the engine bay, mounted mine on the frame rail close to tank, just used the self tapping bolts that came with the pump, not that hard to install. Using edelbrock 7577 airgap intake manifold as well w/1406 - 600cfm 4bbl carb, hauls A.
