your 4779 should be a 750 dbl pumper

The alky carb is most likely an HP series 4bbl of the 750 cfm flavor. There should be numers on the side of the body of the carb, tho, unless the original builder used a blank casting in which case, there may not be #'s there.
17j is right, the 4779 is a 750 double pumper.
Hope that helps,
KP
