OK - I found -

code years option
L48 77 80 ENGINE, 350 C.I.D. V8 (350)

and

Z28 Special Performance Package 20,302 $458.15

Is that all ya get, or is there more specific info to be found like cam, carb etc.

I saw a L79 thread that talked about 3/8 fuel line more as part of that package - so I thought there would be more to it.

I'm a gonna keep looking.

Thanks - Bert
