In Paul Van Valkenburgh's "Chevrolet=Racing?" book, he mentions in the Penske/Donohue chapter (pages 177/178 in the original 1972 edition) that Chevrolet Engineering quietly produced a pamphlet recommending setup information for privateers in 1968.
Photos of the passage are attached below.
Does anyone here have a copy they might be able to scan and send to me - or even simply publish it here? I'm looking for as much technical data on the setup of the Penske cars as I can gather for my book.
I was at the GM Heritage Center this morning, poring through engineering papers on the Z/28 package, but the archivist at GM hasn't seen this document - he's been searching.
Thanks for any help you can give!
