Flathead/Y-block Offy adapter std 4 brl carb on small 4/b base, tapered ports

Description

This Offenhauser carb adapter will work on their flathead 4 brl intake manifold (also Y-block Ford and other apps) to put on either a Carter AFB, Edelbrock Performer or Holley std bore 4 brl. ( AFB or Edelbrock won't work on 48 and earlier flathead engines because of the water outlets).  The manifold base measurement is 3 & 7/8" X 3 & 3/4".   It is prox. 1/2" thick.  Has tapered ports.   Also works on the "Christmas tree", teapot, EARLY wcfb, Rochester 4gc.   Also have this same adapter with straight ports, see other auction. Offy doesn't give you a gasket when you buy one of these but I will include one (#5495 large venturi) so you don't have to order it extra.  This is machined cast aluminum and is made in the USA.   ..   ..     ....   ....  deluxe shoebox flatty stroker tudor coupe sedan 1940 lakes weiand meyer sharp 239 272 292 312 fairlane custom crown Victoria 221 59A 8ba teapot Christmas tree fire hazard
