Edelbrock doesn't sell a chromed pump, just a polished aluminum one for an upcharge over the standard cast aluminum one.

Any factory pump dated coded 1968 or later will be high volume; Ford itself increased the flow as an engineering upgrade.

Dove also makes an aluminum pump.

I see these on ebay, especially the Edelbrock's, fairly often. The Edelbrock's usually run around $125 IIRC, unpolished.
