Just purchased a 71 ss chevelle 1 owner 52,000 orig mile car whith full docs and while i was going over the #s before purchase the eng casting date and front pad stamp are like nothing i have seen before

.While searching for the casting date at the rear of the block there was nothing just the 010 small block eng id # no date.... Finally i found it located right above the starter on the side of the block stamped backwards in ( )

.Then the front pad looks virgin but the stamp has spaces between the assy date stamp like so (example)TO8 15 CNJ but the vin # looks fine

.

CNJ is a 1970 350/300HP 4 bolt main engine code w/Man. trans.
That CNJ prefix was shared on the NON Super Sport 1970 Nova-Camaro-Chevelle-Monte Carlo all using Block casting #3970010.

I was just using that code as an example since i don,t have the auctual code in front of me....I was just wandering if anyone else has come across the odd way that the block was dated or the location of the casting date for a 71 eng???thanks
