Make sure you turn it the right direction if you try this. If there is no oil in the pump it will spin fast when/if it picks up oil you'll know it. Also if there is zero oil pressure the lifters will make a hell of a racket, are they? or are you just going by a bad or disconnected gauge? Did you install new bearings with the cam? Use assembly lube? <img src="/forums/images/graemlins/confused.gif" alt="" /> <img src="/forums/images/graemlins/cheers.gif" alt="" />
