Adapter for old chevy manifold

Hi all i need the chevy experts to help out here.I have an old chevy 4 bbl manifold from the early 60's i think the number on it looks like gm 8788244 but the 8's could be 3's the bolt patter looks to be 5 1/4 x 4 3/8 inches if that makes sense ,now is there an adapter that would get me a nice 600 vac sec on it?...........Marq

 

hello Marq! Sounds like the old carter wcfb,or rochester pattern. I think Speedwaymotors.com will have the adapter you need.Cheers! Glenn

 

i hope they can help as i would like to get a nice carb on it.......Marq

 

Can you not cut the middle out of the adaptor I made? There should be enough meat on it to fit a 4bbl. If you buy one from Speedway thats all you will get anyway just someone else does the drillin'.
