This is what somebody told me that breaks down to:


[/FONT][FONT=&quot]G-1971 model production year[/FONT][FONT=&quot]
[FONT=&quot]W-Windsor Ontario Canada engine plant[/FONT]
[FONT=&quot]340-CID[/FONT]
[FONT=&quot]P-Premium fuel only[/FONT]
[FONT=&quot]3440- Day 3440 is Monday, December 28, 1970 assembly date[/FONT]
[FONT=&quot]0653-Sequence engine built that day[/FONT][/FONT]

Although, the 344th day of 1970 was Thursday, December 10th according to my research...

I would tend to believe that the build date is Dec 10th, as I question if they were working on Dec 28th. Usually the auto industry gets from Christmas Eve until after New Years off with union contracts....
