Every time I hear a about a cam, I think of the early 70's when I installed a lumpy cam in my 340 'Cuda. When I fired it up my father-in-law dropped in and listened to it and said, "Ya got somethin wrong with yer carb. It needs adjusting er something." I told him I had installed a wild camshaft and that was why it was running so "rough." When he died 20 years later he STILL believe that the carb was out of whack.
