Can anyone tell me the correct plugs (and gaps) for a '65 305 V-6? The engine is in a 4000 series (ton and a half).
The engine is not running quite as smoothly as it should and has a little bit of a miss. I am going to pull the plugs to check the gaps, porcelain for chips & cracks, etc. But I have no idea what the gaps are supposed to be, actually ...
A quick recap -- The engine has new cap, rotor, points, condenser, coil, wires and plugs. Also, a freshly rebuild carb with a new mechanical fuel pump with a brand new electric back up (On the way to a show last year, the truck's mechanical pump failed and packed the crab full of diaphram bits, caused an engine fire and caused a lot of issues going home most of which have been corrected now except for this missing. A professional truck mechanic did the compression test, rebuilt the carb and double checked the timing and point gap. We have not yet pulled the plugs and double checked them.
