I had correct carbs on my Hemi 500 and the 68 but that was back when they cost 500-600 each in nice useable condition. My theory is there are many more carbs available than there are cars for them to fit on, same for single 4bbl orange air cleaner assemblies? I've been moving away from original parts for few years now, guess I lost interest in oem. Big cams, aluminum heads, trick carbs and big brakes are really fun. I just bought the whole top half for the Hemi Dart for same price as one set of 70 Hemi carbs.
