Edelbrock S.P.-2P. 318 2V Does it even exist??

Owned one , but have never seen one in a 2bbl. SP2P ...Small port 2 plane? Them runners are like 3/4 EMT. Just put a 4 to 2bbl adapter on it or a plate. Supposed to kick *** in a motorhome or truck or other low RPM app like 2.76 geared cars. Use a small carb too.
