Engine Build and Proper Spark Plug

[Dura]

My apologies if this is an old question, but I would like to know the build year for my engine which seems to pre-date the published information. I would also like to know the proper OEM spark plug as I have seen lengths of 3/8, 1/2 and 3/4. Any information would be appreciated. The engine number is F 248996.

Thanks to all of you.

Btw you can narrow down the engine better with the cast stamp on the drivers side of the block

Thank you very much JohnnyC. Where is the cast stamp located on the driver's side? Where do I find info on it? You have been very helpful and it is greatly appreciated confirming the W14EXR-U plug which has the 3/4" threaded section.

SergP,

I am sorry, but I am not smart about these things. The link with the date list only goes back to 1969 and I don't see where the other link has any info on a driver's side casting stamp. Thank you for your help.

Ok. Not worry we all learning.
Look at this image.
first single number is Year,.. next ..600xx model, ... next Month and Day ( example here 1974.. 1.5engine .. April 22 )
in your case .. year will be 196x and different model

You don't need to remove a valves cover to see those numbers (on the left side of the block)
