Question about Chevrolet script valve covers

Did the OEM stamped steel chevy script covers ever come in chrome from the factory? I was looking at a set and the guy swears they came chrome on some Impalas...Ive never heard this before, is it true?

 

yes they did.

 

Yup I got a set on my 51 Chevy!!! I think they came off a 67 Camaro.

 

1967 or 1968 Z-28 maybe?

 

Ok, thanks guys. I thought I was fairly knowledgeable in this area...guess not lol.

 

I get an education on the HAMB every day.

 

A friend of mine bought a '67 Chevelle 300 (cheap body style 2dr, rubber floor mat with a cloth interior, 350hp 327/4spd, 4.88 posi). It had chrome valve covers from the factory. He still owns it today and is in the process of restoring it.

OT but sounds like quite the interesting car!

 

When he ordered the car his intention was to drag race it. the first modifications were a set of headers and a ****terchield. About this time the GM foundry where he worked (GM nodular Iron in Saginaw, MI, where the small block blocks and heads were cast) went on 7 days a week 12 hours a day. He worked that schedule for the next 8 years with only 3 sick days and 2, 1 week, vacations. The car was used for daily transportation, to and from work, for over 3 years, literally wearing out the drivetrain. He parked it until about a year ago and after retiring is slowly doing a frame off.

Chevrolet offered chrome script valve covers in 1967 only. The chrome covers were used in three instances L79(325HP 327) Chevelles, Z28 and SS 350 Camaros. The L79 was rerated to 325HP to diminish the appeal of the small block. The sales emphasis was on the big block SS 396 option in three horsepower ratings 325, 350 and 375.
1967 was the last year for the vented block for a PCV, vented oil fill tube, and the script valve covers. In '68 the vented valve covers were introduced since the engine blocks were no longer vented. The PCV system was routed from both valve covers. One valve cover hose had a PC valve which ran to the base of the carburetor and the other valve cover had just a hose that went to an outlet in the base of the air cleaner.
Just a little history as to when and why the script valve covers were discontinued.

 

Heres a set of painted script covers I had chromed for my model A project.

Turned out pretty nice.

 

Not that you'd stand much of a chance of finding a pair, but I've seen three '55 Corvettes with chromed script valve covers, which leads me to believe that they were factory issue.
