Small Block Mech Fuel Pumps?

I ordered an Edelbrock 1720 from Summit months ago and just found out that they pushed the "expected" delivery date way into November! Canceled that order and looked for a replacement. I liked the Edelbrock because it had 3/8" ports but would settle for 1/4" if that is all I could get. Cannot seem to find a pump that these places have in stock.
