Use a short rubber hose from hard line along or inside your frame to the fuel pump inlet on the engine.
the electric pumps are noisy, and create other problems and risk areas---do it like was on oem cars running carbs in the 60s and 70s---make sure your tank is vented

I agree, a 640 hp FE (assuming you can make that much as installed in the chassis) with a terrible BSFC as is common with most FE's would require about 53 gallons of fuel per hour or .88 gallons per minute. I would think an HP mechanical pump with 3/8" line could handle that easily. NASCAR engines used engine mounted mechanical pumps a few years ago at HP levels above 800 so why wouldn't a mechanical pump work on a 640 hp engine?
