<< 7 Blade Fan #3947772  dated "A69"  (Jan '69)    Anyone have a clue to what the 914087 next to the A69 is ?  or what the  "L" is that's next to the A69.. BTW that "L" is only on one of the 7 blades. >>

The 914087 is the supplier's internal part number for the fan. That clutch is a later Service replacement, made in 1971 ("G" = 1966, "H" = 1967, "I" = 1968, etc.).

Does anyone know of a place that will rehab an ac compressor?

Classic Auto Air, Tampa, Florida.
63  Camaro Research Group Discussion / Decoding/Numbers / Re: 67 DG rallys on: August 16, 2014, 09:02:59 AM
I have a set of 67 DG rally's. They have no date code that I can find. I heard these were good for that reason.
( No date code).
They are 14 x 6
Any info on them would be helpful.

Are you sure they're 14x6?  I've seen "DG" rallys that are 15" x 6", interchangeable with "DC" rallys.

Does anyone have any idea how Norwood coordinated production of Camaros and Firebirds simultaneously?  ie..  intermixed..  or run firebirds for a day or more then Camaros?? 

They ran Camaro and Firebird intermixed, at a constant ratio. If you kept changing the ratio, every time you did that you'd have to re-balance labor operations and re-assign/re-train every worker in the plant. The ratio was developed based on volume and demand projections, and hardly ever changed.

So is the EGR hose holder clip only on big block?

No 1st-Gen Camaro had EGR, but the L-78 had a clip for the PCV hose that mounted under the right front carb nut.
66  Camaro Research Group Discussion / General Discussion / Re: Original dealer info for 1st gens is available on: August 12, 2014, 11:09:40 AM

I've read where you said that before, and I'm not doubting you..  I'm just using the data (by month) that CRG provides us.

For the 912/day to be true... the month end totals would have to be off by *several weeks of production* if true.... and there would have had to be a LONG shut-down time that summer of '69 before they resumed production...??    I recall reading in some car mags back in 69, that salaried employees ran production for awhile.. during an 'hourly' hold out or ??  and if so, their production rate would have surely been less...    Can you shed any light on that?

A lot of those magazine articles were "fairy tales", written by folks who had no clue about how manufacturing plants operate; salaried employees didn't man the line and build cars. How many cars do you suppose 100 salaried guys could build, replacing 4,000 hourly assemblers spread across 16 miles of conveyors? None - it's a fairy tale.

I have some more technical articles to add - just need to buckle down and clean them up so Bryon can re-format them.  Smiley
68  Camaro Research Group Discussion / General Discussion / Re: Original dealer info for 1st gens is available on: August 11, 2014, 10:40:22 AM

your number, 643537 was the 6431st Camaro that month.    ie.   6431 of 13,217 during May.   There was 21 work days that month, so Norwood produced an avg of 629 Camaros per day.   

There are some holes/errors in those Chevrolet-provided numbers, as the line speed never changed - Norwood built 912 per day, every day, even if it took overtime to do so.

My only reason for leaving the tubes in place is the 30 degree countersink under the tube - the tube seat seals that, then the flat nail head seals the top of the tube.

That's why I use the #10 x 1/2" flat head machine screws - they have a flat top, and a 30-degree taper on the bottom that matches the countersink in the manifold that would normally be sealed by the tube nut.
70  Camaro Research Group Discussion / Maintenance / Re: 67 gas cap on: August 07, 2014, 09:42:48 AM
The cap contains a 2-way vacuum/pressure valve which allows air entry to replace the volume of fuel used so the tank doesn't build a vacuum (which can result in fuel starvation or partial collapse of the tank), and allows pressure relief at a certain pressure level to avoid distortion of the tank. Both sides of that valve need to be working.

You can use roofing nails (galvanized) in the extension tubes - seals off the extension tubes, flat surface to seal on. Drop them in, tighten the tube fitting and you're all set.

My opinion - others ?

Regards -

That leaves both the extension tubes AND the roofing nails in the exhaust stream - I prefer to knock out the extension tubes and use the #10 x 1/2" flat head machine screws to plug the holes; leaves nothing at all in the exhaust stream.
72  Camaro Research Group Discussion / General Discussion / Re: ebay 302 on: August 02, 2014, 07:06:17 PM
I sent him a note and told him it was a really bad re-stamp, since all DZ 302 engines were built at Flint (V), and none were built at Tonawanda (T). His response?  "Yep."
73  Camaro Research Group Discussion / Originality / Re: Anco Aero Wiper Blade ID on: August 02, 2014, 12:42:14 PM
By the way, I've seen these as early (bright polished) editions, and the matte finish late models, on Corvettes, plus the 18" blades on Mopars. They may be aftermarket, but I've seen a lot of pairs sell for large prices, plus even Classic has them advertised in the catalog as repops. Coincidental, I'm sure.

The "aero" wing blades were never used on Corvettes, either; both Anco and Trico blades were used (in pairs) on '63-'67 Corvettes, but only in the normal (non-"aero") configuration. Vendors will tell you anything to sell you parts, and I'm sure more than one has tried to sell "high-performance cars got hiigh-performance wiper blades from the factory".  :-(
74  Camaro Research Group Discussion / Originality / Re: Anco Aero Wiper Blade ID on: August 01, 2014, 10:56:51 AM
The "Aero" (wing) feature was only on aftermarket blades - none were ever used in production.

It's not even a GM part - it's a Hurst aftermarket knob.
