First, were all the heads that were supplied with the Trac Pac packages
"C" heads with the plugged smog holes?
My best recollection is that all the '66 4-4-2's had "B" heads.

From what I've read, the only emission "C" heads were on California cars.
Was there anything else visible that would distinguish Trac Pac equipment
from the basic 4-4-2 stuff?

The reason I ask, several years ago, I bought a '66 4-4-2 parts car (unfortunately too rusty to restore).
It had been parked in a field for probably 20 years before I got it.
It had a non-original, but complete and correct, tri-power.
It was a 4-speed, 3.90 posi, manual steering car which had been raced.
This engine has "C" heads with plugged emission system ports (See pic).

It was a no frills 4-speed car, no power steering or brakes, with a racing history,
so, it was the type of car that the owner may have up graded for racing.

I still have the drive train and was considering using it in my '67 4-4-2 ressurection project.

Just wondered if there's a chance this car had a Trac Pac package installed.

On the off chance some of you old timers (like me ) might recognize this car,
it was in the Ohio State Championship at Thompson Speedway one year.
It had a dash plaque from the event.
The "7th Annual......", whatever year that was.

From what I think I know the 66 W cars had B heads and 67 C heads. C heads were not used until 67. The 67 cars had the smog type heads and I dont know about the 66's. You should refer to the cars in question as W30 as it has been generally accepted that the Track Pack cars were the ones converted and not factory produced. In 66 the OAI bezels in the bumper required the parking lights to be moved inward in the bumper. The car you pictured has them in the stock location.

Run to Rund

When was the car built? All L69s were build Dec 65 or later. All 66s had B heads. I have been told that all 67 W30s and other cars destined for CA or bordering states had AIR heads. The factory had special plugs for those holes if they didn't install AIR on the car. I also believe that replacement heads of the era came that way so one part number would serve all buyers. As above, that front bumper never had OAI bezels in it, and if the radiator side baffles aren't cut out, it did not have the 66 OAI at some time.

My 67 had one correct C head on it, fortunatly the one on the passenger side with the 442 V200000 number. The other one was a big valve B head. It had the smog pump, so the ports were drilled, tapped and used for the smog junk. Also im pretty sure the 67 W30's also had tapped smog ports, but were plugged. Im not sure about the 66 heads. I took all the smog stuff off, and got another C head, its not tapped but i dont care. I still have the tapped B head, but the machine shop took the valves out of it and i never got them back.

I forgot to mention the '67 "W" cars.
I had heard they were all the smog heads with plugs as well.
I never thought this car was an original OAI or L-69.
I thought maybe the owner decided to add the Trac Pac parts, maybe the following year,
using the tri-power, heads, camshaft, valve springs, etc,
possibly just not bothering to install the ram air stuff.
That would explain the "C" heads.

I guess the best way to pin this down is to ask if there were any special
characteristics unique to the Trac Pac heads, like extra large valves or unique markings,
that would confirm what they are.

The 67 W-30 factory cars had plugged, worked AIR C heads along with a whole bunch of other stuff, including the OAI package and cam. The track pack was simply the OAI package and cam, in an otherwise standard 442 67 400 engine, with the large valve normal C heads. One way to check a 67 is to look at the holes in the core support for the air inlets. Nice stamped ones are factory W-30 cars, sawed ones are track pack add ons.

Oldsmaniac

What work was done to the heads? I have never heard of the heads being worked only being the smog AIR heads.

Joe, I have no idea.
I pulled the drive train when I disassembled the car several years ago,
stashed it and haven't touched it since.
I can only say that visually, the valve springs, keepers and retainer
do not appear to be original equipment.

I guess the question should be rephrased to ask what was different
about the W-30 heads since that's what was in the Trac Pac package.
Is there a way to verify they are W-30 heads?

I'm guessing the heads have been reworked to some degree, but,
can't say exactly to what extent.
The work I'm seeing isn't from the factory.
The engine as a whole may very well have been reworked to some extent.
Since my renewed focus on this engine, I've become more curious about all this,
but, lately I haven't been up to getting into it as I'm just recovering from a series of chemo treatments.
Just getting back to normal the last few days.

Gonna try to pull the heads this weekend and figure out what I have.
Sorry I don't have more specific info right now.

Ok. Time for this geezer to add my $.02 worth.
Lets start by clearing the air about track.pack option on a 67. Track pack had NOTHING TO DO WITH HEADS. cam and valve springs were only engine parts in the track pack.
That answers that. Stock C heads on original car that was being converted with track pack remained the same with exception of valve spring upgrade.
Next: ALL 67 W 30 cars had Smog C heads with special ugs in the holes (not ordinary pipe plugs). ALL W30 heads were made using castings all cast during the one month period of from 1st week of Dec 66 through the 1st week of Janary 67. It is believed the majority of them carry casting dates un the 340's ( mine were both 343).
Now KODA, as for "work or working those W heads). Nothing special was done to any ports or any bowl work. What they DID DO , was to make sure they were under 75 cc in volume(NHRA min was 72). As you may know, most stock C heads check out about 78-80cc. As some may have rumored, they did NOT have multi-angle valve jobs on them from the factory. Hope this clears up the questions about the 67 W30 cars.

hurst68olds

as Tweed stated NO such thing as "track-pack" heads

WAG you have a '67 W30 engine under a '66 3x2bbl set-up

what's the VxxxxxxG number stamped on the passenger side head?

Koda

Maniac, Ed, Tweed,

Thanks for info, I just meant they had been tightly specified and blueprinted like Tweed said. I should not have said worked, which implies machine work.

Ok, I have a question, since it's what I am doing to mine. If you had a 442 with AC and bought a track pack from the dealer, how would you route the air hose? The 68 HO with AC just runs it over the compressor back. I was thinking of moving the AC muffler for clearance for the OAI hose.

Oldsmaniac

I would say you will have to run the air hose where you can. If it requires moving the AC line then that is what will have to be done. You dont have a lot of choices. I would guess that it was not common to install the OAI kit on AC cars. My feelings are that mostly racers bought the over the counter kit to race and would want a lighter car with lesser options and bigger gears out back, something AC cars did not have. Here is the breakdown of parts included in the OAI kit from the dealer.

KODA , the OAI hose will go over the AC line and compressor on the 67. Remember the alternator moves to the other side on AC. There is even room in there for a smog pump ala Calif cars. I have a pic somewhere of a california W30 with AC and you can see how the OAI hoses will go over the AC lines. Maybe Maniac has it? I may have given it to him? Good luck with your project.

Does anyone have a crisp clear OAI kit from the dealer list sheet?

joe_padavano

Here's the 1967 page

Andy

I have a decent copy..Curt Anderson gives you a packet that includes the factory OAI kit for both 66-67 I believe along with factory instructions on install. When I track packed my 66 442 I bought the bezel and hose kit from Curt. Its a copy obviously and not a frame worthy copy. I can verify ifyou want.. You can have it. Its not as nice as the doc Joe Padavano posted above

Koda

Which of the Andersons sells the repro parts?

Andy

Curt Anderson is the only person I am aware of the sells the kit for 66-67 cars. If you want his info let me know I will PM it to you.

Koda

I've lost his email, so please.

It is widely believed that all '67 W-30s came with a K-19 delete engine assembly, which had the plugs in the heads and a curved oil fill tube, though some say they have seen K-19 engines without the curved tube.

Notice on the list is the rarely mentioned power steering hose.
