70's cars... Challenger, Duster, etc

Can't wait for the pics.
What year is the road runner?
I might be interested in a 383 if the date code is correct. Looking for September of 1969. Very early production for 1970.
I would be interested in any big block if it has e-body vin stamped on it.
Hey, this is post number 100 for me!! Took almost two years to get this far.
