After her Mother's passing her Dad sold it to a friend for a few years, now it is in the Chicago suburbs. Today Nancy showed me a pic of the car on the cover of a JC Whitney catalogue. She is in contact with the owner and they plan to get together at some point.
I remember being impressed by the HO engine's free flowing exhaust manifolds. - Bill W

Good morning Mr. W,

Thank you for posting such a cool vintage photo!
Looks to be N code Burgundy with Black Cordova top and White pinstripes.
Custom wheel disc.
White line tires.
Looks like a Custom Sport ‘wood’ wheel.
Dealer name plate.

I’ve had several 1967 HO cars and many ‘66 Tri-Power cars and I can tell you these two cars are almost neck and neck, but that HO will prevail at the end.

Many unique components to the ‘67 HO that make it special.

Massive exhaust manifolds.
These manifolds barely clear the chassis and get extremely hot so a stainless steel shield is fastened to the top of the starter solenoid. The HO solenoid is a first year design “348” with a solid steel cap, unlike the brown Bakelite found on other solenoids.
A special engine wire harness is used that has the two starter wires routed in a long U turn. Up to the front of the LH side of engine, down the front and back to the starter traveling through an oval metal tube fastened to the top of the LH engine mount. This also requires a special positive battery cable that goes through that starter wire tube. These are a PITA to deal with when servicing a starter.

The 49 state HO used a large round air cleaner.

You're welcome Chris, I thought you might like it!

Thanks for the details of the HO engine, Pontiac really stepped up for that one!

The Feldman building has housed an overhead door company for decades, I snapped some pix while being prepped for paint a few years ago. - Bill W

Morning Bill,

I’d say you were fortunate to have been in that neighborhood at the time someone was prepping the building for paint to capture those historical photos.

I tried to clean up the two photos a bit.
First one is obvious.
Second, not so much other than the Pontiac crest.

Thank you for these vintage pics to go with the ‘67 HO.

Chris.

For those interested in more information on the 1967 GTO equipped with the optional HO (L74) and RA (L67).

Below are a few factory illustrations about the U-turn engine wire harness that’s required for these two models fitted with the large exhaust manifolds.

Interesting details Chris! I remember similar cable routings from my short tenure at a Pontiac dealership in the mid 70's, not sure on what specific cars though. - Bill W

That's a great illustration.

When I put my '66 together, I didn't like the way the factory put the positive battery cable routing up between the exhaust manifold tubes to the inner fender- so I was planning to fabricate a routing tube to do just what that '67 HO tube does.

Then I discovered the factory '67 Tube- and just bought that.

But I didn't like or want to route the starter wires through that same tube- then up & around the front of the motor- so I modeled a custom tube, and 3D-printed it to route those wires up the back of the block.

BTW- that tube is printed in Ultem for any of you folks wondering if a polymer will hold up to the temps.

Looks nice but why not use the F-body metal tube which mounts and runs in the same location?

Saw that, looked like a '68 only piece?
Wasn't sure it would work with the header tubes, and I seem to recall I couldn't even find one available for sale in a search- only images.
Quicker and much easier to model one and print it and had it ready to go in a couple hours.
