: Help identifying valve covers

Aug 1st, 12, 08:19 AM
I have a set of big block valve covers that I believe are form a '67 Ca. AIR equipped car.
They have two "indents" that I have never seen on any valve covers.
Please look at photos below and let me know what you can.
Thanks in advance,

They are not from a 348 or 409 Chevy Big block. I can't guess what engine they are from.

pre 68 Looks like the tabs were mig welded along with spot welded. The calif. smog covers I've had and seen don't have those notches. I wonder if those notches are for an a/c bracket on chevelle's

Look like late 60's Corvette Calif/High Altitude RPO-K19 A.I.R equiped 427 covers.
Thought 67's were painted and 68~? were chrome - but that's a "JohnZ" type question ... :thumbsup:

The diverter mounts in that bracket.

They must be Chevelle covers; they have the curved bracket for the '67-only K-19 mixture control valve, but Corvette covers were all painted (except for 16 L-89's, but none of those had K-19). Have never seen those square indentations on Corvette covers.

The only other application I can think of may be a 1967/68 Impala.
I did a engine rebuild on a 1968 Impala SS-427 'California Car' quite a few years back and it had some 'odd' covers on it that I send out to re-chrome - passenger's side had that K19 diverter valve mount on them ...
It also had a couple small 'dinks' to clear the AC Compressor bracketing system, but I really don't recall exactly how many or where they were located :o - just remember thinking 'oh, that's why those are there' as I put it all back together. (I didn't take it apart - PO had ...)

I took pictures of the block, long-block and a few other things while doing the work back then - but a quick look through some of my slides (:yes: it was that long ago :p) didn't show any photos of the finished passenger side that showed covers detail.

To bad there's no identifier decal on one of the ends ...
I can't remember any Chevelle applications like that.
And that Impala would have to be my best re-collection - and I'm old ;)
Sooooo ... if JohnZ can't identify them then I'm afraid you quest for their OEM application must continue :thumbsup:

My guess is Impala. I am looking through all of my Chevelle engine pics, but have not found anything yet.

Post them over on Team Chevelle.

I have asked a couple of Chevelle experts and will let you know what I find out.
