[69 Post Sedan]

I hope your close Dan but I'm not too sure about the whole numbers thing on the dyno. I think the real test will be at the track.

Mark, we do have a set of the aftermarket tabs for the valve covers, they weren't on yet.

A friend of mine that lived down the street when I was growing up had a '70 Chevelle with a 427 +.125 and 13.5 to 1 slugs. He had those valve covers on his motor which was back in the late 70's early 80's. I thought they would look somewhat correct plus I needed them to clear the stud girdle.
