oledoc - my 70 1/2 was Orange with White stripes.
As far as which one was the top of the line Z-28 or SS. The SS you could get a 396 as I recall. The Z cars were 302's then 350's. Both were very fast.
There is a Yenko Camaro that shows up just about every week at our Cruise Ins. Those were plain jane Camaro's and Nova's with 427's in them. They all came with the pie tin hubcaps. Would have loved to have owned one of those!
