Tech1, Glad it worked for you! My engine has been sitting with oil in it for almost two years with only an occasional turn to set the valves but I plan to add plenty of the ZDP stuff when I get to the startup event. Just for the record what is the correct direction for a SBC350? I usually set the drill for clockwise rotation but it is easy to reverse on my Craftsman 1/2" drill. I have twice reved up the device to run the oil pump just to keep things wet internally but I used clockwise rotation. Comments?
