I would use an old Ford distributor with Pertronix internals for a vintage look.
Holley vac sec 4150 series with LeMans float bowls on the ends.
Ally water pump is fine, paint it. If you want a cast iron water pump I have two here available for free if the new owner covers shipping.
Ford pulleys are readily available as new or good used.
I would use an Autolite alternator and a voltage regulator.
