Talks about Julian date codes on the blocks.
Why is it you need to find this out? Its obvious that its not the original motor for this car.

The year of the motor won't do you any good with tune up specs. In stock form, the 307 used the Computer Command Control (CCC) system that electronically controlled spark advance, mixture ratio, and a host of emissions equipment like the EGR valve and the A.I.R. system. I assume your car does not have this hardware, so someone has installed the non-computerized carb and distributor from a different year and engine size. You'll need to use trial and error to find the right adjustments, I'm afraid.
