is it or isn't it California 69 Big Block??

[chris slawski]

Need some expertise please.
I am going to look at a 69 Camaro from the California plant. The car is being said to be a big block car, but no engine, no trans. I am not sure if it has a tach to check the redline. It supposedly has the original 12 bolt rear 3.31 open carrier. It does have a big block heater core, and is disc brake equipped, there are no fuel lines in the car, but appears the sending unit is on the fuel tank. No build sheet, no POP. I am going to pull the rear seat if possible to see if any x-code written on the bulk head.
Any other thoughts where to look?
Based on this information what would YOU consider it?
Sorry if worms are now pouring out of the can.
