Gibb Chevrolet docs

[William]

Since 1989 when Fred Gibb gave Bill Porterfield much of the original paperwork from his dealership, I have been pestering him about what would happen to the docs when he tipped over [he’s 10 years older than I]. Told him his daughter would probably heave it into a dumpster. Despite promises and assurances I heard over 34 years, nothing came of it.

Backing up a bit, late 2019 out of the blue I heard from an individual that had privately acquired a Gibb ZL-1. Related the story about the dealership paperwork and referred him to Porterfield for the paperwork on his ZL-1. They hit it off and voilà, he recently acquired all of it from Porterfield. He invited me to visit for unfettered access; free to copy anything I want.

So that’s where I was this week. 10 hours was just enough time to buzz through the literally hundreds of folders in a dozen cartons; everything from letters from John De Lorean to engineering drawings of the ZL-2 hood pad [too big to copy]. Still has about 25 original ZL-1 shipper’s copies and a few PDIs with the POP imprint. Some info on the ’69 ZL-1 show car; a folder with several original decals for it. Finally, have complete copies of the ZL-1 Engine Assembly Manual. There are two versions, one noted COPO 9567 [show car]. I flew with a carry-on only, limited in how much I could bring back.

Also, docs on the 50 ’68 COPO Novas, the first TH400/L78 cars Chevy built. No shippers on those, but a number of PDIs with POP imprint. For some reason, a number of docs concerning the later big bore Can-Am 430” block that most racers switched to for the better bore/stroke ratio.

The info did not include every ZL-1 Camaro or L78/auto Nova the dealership acquired.

This was just a beginning. A more thorough review is planned for a later date. The desire is to eventually reunite docs bearing a VIN with the vehicles they belong to. If you have a Gibb car w/o documentation, pm me here.

This is amazing news William. Your patience and persistence paid off. Hopefully the originals will find a more permanent place for final resting.

Amazing stuff!!!

I had the honour of spending an evening with Bill recently and he came to PSMCDR to be with the MSU Project W31 gang. He ever so quietly showed me that the bolts on my steering rag joint were coming loose (so he saved my butt)

He has a treasure chest of information and especially Dick Harrell everything.

He even wore a shirt completely covered in Oldsmobile:-)

I met Bill a handful of times many years ago, and helped him at Indy the weekend of “the fire”. We also had a mutual interest in Oldsmobiles; not hard to figure out he really was an engineer. I firmly believe he is responsible for the overwhelming interest in the ZL-1 cars, and doesn’t receive the recognition he deserves for uncovering the history of them.

Totally agree!!!

There is no question Bill Porterfield was the catalyst for the Camaro ZL-1 body of knowledge. He was recognized as such in the COPO Camaro story that has been on the CRG site for over 20 years.

He never sought personal recognition; the cars were the stars and he did a fine job of promoting them over the years. Beginning with the March 1983 Hot Rod Magazine feature on the discovery of ZL-1 #3, over 15 feature articles were written on #1 and #3. The story continues to this day; Hemmings Muscle Machines recently published a 2-part feature on ZL-1 #11.

As we were poring over the many boxes of documentation he assembled over the years, it occurred to us that none of the original material likely exists anywhere within Chevrolet.

Persistence may be annoying, but the end often justifies the means.

Wow… this is awesome ! Congrats William . Well deserved knowledge of information!

Bill actually contacted me after finding out I owned ZL-1 34. I, soon after, reunited the original Gibb paperwork with the car. He mentioned at the time that he had a POP imprint, but it was not included when the package arrived.
It was still cool to see the original docs signed by Fred documenting the car’s journey to Gibb Chevrolet and then getting picked up and returned to Norwood !

Wow! So great that you are archiving these documents. They are indeed treasures. For those who have not had occasion to ask William for information in the past - I can tell you that he is always responsive. He is always there to help. He is the perfect individual to catalog & archive this material.

Thanks for all you do Bill.
