				 Re: Casting date  versus assy date curiosity 
 
			
			For what it's worth, my '70 SS 396/350hp has a build date in the Sept/Oct '69 timeframe. My vin is a 10W144xxx.  The 10W3xxxxx definately is a later production. I've also had some '70's built in June and they were around that numbering sequence.
