Originality / Re: 69 CAMARO COWL INDUCTION AIR CLEANER
« on: September 19, 2018, 02:57:55 PM »
I don't know for certain that's why the change was made. Not mentioned in any Chevrolet service bulletin. But it makes sense. Considering the variables involved-air cleaner stamping, carb gasket thickness, element height, depth of insertion of the vent tubes, it may have been possible. Appears to have been intermittently phased in. I know of a Sept '69 Z/28 with a revised base and an October '69 Z/28 with a flat base.

The 90º vent tube may have never changed in production. It was only a problem on Holley DP carbs. ZL1s were supposed to be built with the 850 DP but most were not.

I believe under certain conditions there was an air flow restriction with the original flat-bottom. Elevating the element would eliminate the problem.

General Discussion / Re: BB curved neck radiator

My last career stop was as a Supply Chain Analyst for a company in the automotive industry. I had responsibility for a low volume radiator, maybe 5,000 units annually. The supplier was sold to a larger company and they wasted no time no time notifying us they would no longer supply the radiator. In researching history, they were the 3rd supplier in 10 years.

Suppliers like these don't want low volume production. They take the business when they have available capacity and drop it when they need room for a better customer. I'm sure you have heard the stories about how the auto industry pushes its suppliers around. In many cases, there are few suppliers worldwide with the capability of producing the quality and volume you're looking for and they know it. They can be just as tough.

BTW the radiator was for a vehicle still in production. When the vehicle is no longer in production, it can be very difficult to convince a supplier to continue to service it. They may offer one last production run to cover the service life of 10 years. Cost is often higher. You have to service it so you're stuck with the inventory. Getting to be very common with parts having a circuit card, like fuel pumps, key fobs.

HBC is in no position to dictate terms to a supplier of radiators.

Warranty short and fitted blocks were made to order. Looks like a 1972 build. Unless you have paperwork showing the replacement, no telling how it got there.

Scroll down to "Service Engine (CE) and Transmission Coding"

That's a repro dash top. VIN tag has been off the car.

Transmission VIN derivative stamp should match the engine VIN derivative stamp so we will want to compare them.  They were both done at the same time with the same setup according to normative practice.

That is not always true. There are documented original cars with correct VIN stampings that do not match.

The 1st pic shows the generic GMPD service unit available into the '90s on the right. Could also be the repro. It has the vent tube with 2 45º bends, not known to have been used in production. Also has the bead in the base to raise the element. The other unit has a flat base and the 90º vent tube, almost certainly a production unit. There were three versions of the flat bottom:

6485233 L48 w/manual trans...coded DE
6485234 L48 w/auto trans-has vacuum valve in the snout...coded DF
6485235 302, 396/427...coded DG

Not full gloss. But definitely not flat or satin.

Decoding/Numbers / Caveat Emptor...check those tags

Repro body tag. VIN tag was removed when dash top was replaced.

Proceed with caution.

I compared it to a known real March 14 DZ engine and think it may be ok.

Need to remove the paint to verify broach marks.

No, orange and yellow were introduced early February '69.

If our db is any indication, orange was initially allocated to Z11s. 1st 714 is 1st week March; 1st coupe w/720 is mid-April.

Looks like JL8 option pricing wasn't known until early February. The first cars were built a few weeks later, likely ordered without knowing the cost.

Glossier than that. This belongs to a local car, one owner, apart since 1972.

Azure Turquoise [55 55] is a rare Camaro color for '69. Based on our small db, about 2% of production. But, very unusual on a Z/28.

Too bad it was repainted black. Very expensive to correct.

If you wanted a rare Z/28, check this one out. It's black now but was originally Azure Turquoise.

Chevy option info back in the day was often inconsistent; you really had to read the fine print.

JL8 ordering info is really flaky. JL8 info for Canada initially listed "w/Camaro SS" and "w/o Camaro SS." By February it states "Z28 and G80 must be ordered." As of May 1, Camaro SS and w/o Camaro SS was added and states “…also includes F70 x 15 Fiberglass Belted White Stripe Tires.”

It may have been technically available, but that is no guarantee they built any. I can’t imagine a Chevy dealer ordering a 6 cylinder Camaro with JL8 without a huge deposit, maybe 100%.
