(quoted from post at 18:35:03 05/29/16) What spark plug does everyone use in there C ?

Look at the cylinder head and get the number cast into the LH side of the head between the spark plugs, If the head is the standard low compression head there is a good chance it has the large base plugs, the later heads took the smaller 3116 which is my recommendation also but that older head took a different plug. Remove a plug and get the number off it and get back to us.

i dont see any casting numbers, it is an early C with flat belt water pump,

I would bet that if the plugs go straight in the side of the head that it has the large base plugs. Remove one and measure the diameter of the threaded area.

3076 Autolites if it has the 4570 head (7/8" straight plugs)
