Is 6.760 stock 440 length or shorter, say the length of a BBC rod? I have stock heads and 440 rods so I am thinking the diamond 4.3750 and am looking for 10.5 to one with stock head chamber (452's w/2:14 intake)(88cc? I think) and I have been leaning toward a roller cam. I would think they would last longer and be less drag on the HP right? Is the 800 a duel feed /double pumper?
