Best intake manifold and carburetor for a 273

eddy performer with a 500~625 carter/eddy afb or AVS 2
(and that's performer, not RPM or air gap)

if you could find one and don't mind splashing the cash, eddy LD4-B would be awesome.

**double check that you have the later heads** early units had a different bolt angle and take a specific intake manifold that is unique.

are you going to do a cam as well?
