Hey guys, I have a chance to get a brand new NOS 2bbl carb of either brand for my '68 383. The Carter is the correct number (4423s). Certain places on the net state that the Carter, by virtue of fuel rods as opposed to jets, offer slightly better fuel economy. Anyone ever think about this comparison. I know Stan and others have the Stromberg and like it. Is it better or easier to tune and keep alive. Thanks!
