Let General karthief et al. steer you in the right direction
Wait, they rarely let me off the property and I don't even have a drivers license
the timing cover swap can be intimidating, an in tank electric fuel pump is another option but can intimidate too, wiring, fp inertia switch, and it may need a return line and a regulator.
A quick search I got a Jegs that claims 66-93 sbf that fits both water pump directions, choice of timing pointer locations and dipstick location for the early models and the FP boss, now the FP eccentric is another question, that I don't know about. Will it fit on the roller cam? I don't know.

You could install a inline, external FP, it needs to be by the tank and ideally at or below the bottom of the tank but they run constantly and are prone to failure because they run constantly and can get hot which causes them to fail.
My vote would be the in tank fuel pump. I think there is likely a low pressure model for carbs. Do some research, you have options.
Sorry about the long post, I'm on a coffee buzz.
