The engine stamp date - T0606 is probably the correct date - consistent with my protecto place and close to your car. The question is, with the stamp date on the block - and the actual trim tag build date on the trim tag, 07E, the question is - was the block assembled at the time of the stamp date or was the short block only stamped and the rest of the engine accessories (heads, carb, distributor, water pump etc) installed later?

If the engine was complete at the time of the engine block stamp - then the dates could be a month or so before the engine stamp date. If the block was built later at around the body assembly then later dates for components would be appropriate.

Having said all the above, as i shared earlier, there are anomalies, like the transmission stamp date 8B - that 6 months before the car was build and it was a simple M21 trans, nothing unusual.

Others may have some thoughts - better experiences on this topic.
