DADS50 I believe I have made a mistake. I thought it was a 235 but I believe its a 216. I have not been working on the motor long. I have spent most of the time I have had the truck rewiring and handling smaller things that took less time. I was in between moves. All I have done is put new spark plugs, cap and rotor button, wires, ignition coil, rebuilt the carb. Things like that. I noticed today when I pulled the valve cover with the engine running that there was some huge gapping in the valves. Also I believe two rods were bent because they were not going straight up and down. They were dancing around a pretty good bit.
