Couldn't get into factored HP for 1969 ZL1 on NHRA website. Anybody know what it is? It's a stick car. Also, when I was looking at the specs for this engine the other day, it said outer spring with damper. It used to say outer and inner spring with damper. I know the factory used inner/outer with a damper back in 1969.
