Early Y Block OHC 239 Spark Plugs
Did the early 239 Y Block have 18mm spark plugs, or, 14mm? Heard it both ways. I argue this once a week. Please, someone put this to bed. Thanks.

14mm. 1955 was the first year for the tapered seat 18mm. (If I'm remembering correctly)

Re: Early Y Block OHC 239 Spark Plugs
The EBU 239 had 14 mm - the EBV 239 (most of these ended up in trucks in 55) had 18mm.
Of course, over the years people have changed out heads, blocks, and the whole gamut. I have disassembled several Y blocks that had mismatched heads.

Thanks, for confirming. I thought I was right, but, have couple of buddies, who didn"t believe me, so, I wanted to hear someone else say it. Thanks for your time.

FORD used CHAMPION from 1955 until they bought certain parts of AUTOLITE (but they won't), wanting mostly the SPARK PLUG DIVISION.
