I am not much up on cam specs and what they mean as far as degrees. So, I assume a cam could have a comparitivly long duration without all that much lift? . My cam measures approx .475 lift on intake and exhaust and looks like quite a bit of duration. Could that be why I have very little vacume on a gauge? I know I don't have any leaks.....................................MO

A friend started up his El Camino, and I thought from the clicking sound it made, that he had an electric fuel pump. No, he said he had to put on a vacume pump for his brakes to work right. I had never seen one before. Is this common among Mopar engines with certain cams?.........................--......MO
