K Kentf1003 Senior Member Dec 18, 2010 #1 I'm putting a 1946 Ford 59AB engine in my 40 pickup. What Champion plugs were original? Thanks.
Old Henry Well-known member Dec 18, 2010 #2 Champion H10 were the originals. Now you have to add a C after the H10 to get copper cores. So, the modern replacement is Champion H10C
