First of all regarding the date code theory. Pontiac did make some Ram Air V blocks in 69.They were in fact developed for Trans Am racing (303CID) and strip tested in a 69 GTO (400 cid) first. Are you trying to say that if this motor pre-dates the car that it is the real deal. Well I don't believe that. It just means someone purchased a date coded 69 block.

The block in the artcle Mrs Billybobcat attached was date coded 70. The serial production number you are trying to validate is later in the sequence and should have a later date code. If anyone knows RA V's the Shultzes do they have a lot of documentation and a car that is documented.

A 69 car with documentation but a 70 car without, why do you think someone would not document that 70 car? It's only a year later. [img]/ubbthreads/images/graemlins/dunno.gif[/img]

Things that make you go hmmmmmmmm!
