Re: Need help with my first 350 sbc
You could always run a compression check and that should give you a good idea of the motors health. A flat cam is pretty easy to see. Flat lobe on exhaust will labor hard and backfire since the intake charge can't get out of the cylinder and a flat intake will be an obvious miss. Either condition. Should make a vacuum gauge eratic. Set the idle really low so it barely runs. Pull that valve cover and watch the rockers move as it idles. Usually the motor won't sling oil everywhere at 4-500 rpm. I have replaced several flat cams over the years and only got bit once. That one lost oil pressure so I rolled in a new set of main bearings and it lost pressure again the next day.
