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

Ok guys, thanks. I've been reading up on Magnum swaps but never saw that question com up.

So even if I go carbureted, I still have to go electric fuel pump and of course some kind of pressure regulator to bring the psi down before the carb.

Just trying to find the cheapest way to do the swap. I have the.cash to pick up a nice 5.2 or 5.9, but it's the cost of all the extra stuff that's going to put me in the hole, or keep the car off the road longer
