Can not call this pure stock, in 72 you could change the pan and use after market pistons just to name a couple of things. When they restarted Stock in 74 or 5 it went back to oem pistons and parts.

1972

* No Headers
* No Slicks

{Classed in C/S or C/SA} = {11.00 to 11.99 Wt/Hp}

No Headers, and full stock exhaust, but you could have exhaust cutouts.
