I have a 1985 GMC Short bed pickup with a 305 in it. Trying to read the timing mark directly under the water pump is unreal. I took off the fan and water pump pully, all the belts, shroud. It has 4 V notches. Where is "0" and 4 degrees BTD? There is a very wide notch towards the drivers side. Is that zero?
have the same problem?
