1051  Camaro Research Group Discussion / Restoration / Re: need a transverse muffler for 69 Z , on: August 01, 2006, 12:13:35 PM
It is fact.

Bill Porterfield did a series of dyno runs on a ZL1 engine. Disconnecting the chambered exhaust picked up around 80 hp.

Todays' 3" flowmaster X-pipe systems cost virtually no hp.

Nope, both of mine had floating pins.
1053  Camaro Research Group Discussion / Decoding/Numbers / Re: COPO? on: July 26, 2006, 12:26:34 PM
This a fairly common question on many of the 1st gen boards. The responses are predictable-look for this, what is the body number, etc.

None of it is proof the car is a COPO. The only proof is original factory paperwork or an unquestionable, original VIN stamped engine.

Cunneen has knowledge of the cars but no one has Chevrolet build records. I believe he no longer "certifies" cars.
If you have any reason to believe the car was sold new in Canada you can get info from the Zone office there as they still have records.

Your next step is to start tracking past ownership. Maybe someone has paperwork or the motor. Long shot but worth it. There are many near perfect COPO clownes out there. No one trusts undocumented cars these days.

Yup; car had bars and big rubber on a "BO" code 3.73 open.

Something broke, probably the rear U-joint, and when the driveshaft got loose it acquired a dent. The blacksmiths that repaired it re-installed the now-unbalanced driveshaft, trashing the pinion bearing. When I acquired the car everything in the housing went in the dumpster.

In all my years I have never heard of a driveshaft failure on a more or less stock 1st gen. 2nd gens are another issue. A friend twisted one into a knot on a '70 Z28.

I'm not nagging but there were almost 700,000 1st gen Camaros built and conclusions are being drawn based on a couple dozen datapoints.

I've been involved with the cars for over 30 years and the Z/28 driveshaft issue has been out there for as long as I can remember. It became an issue because most driveshafts at the time had in-line yokes. 30 years later we still do not know why some were different.
1056  Camaro Research Group Discussion / Originality / Re: 1969 z/28 driveshaft on: July 16, 2006, 01:05:57 PM
We had a Camaro parts business for 15 years and always kept driveshafts from parts cars for resale. In line yokes are the norm. When my 69 Z/28 driveshaft [offset yokes] needed to be replaced due to previous abuse my good friend Stevie at D & R provided me with the 'shaft out a L35 parts car-in line yokes.
1057  Camaro Research Group Discussion / General Discussion / Re: VIN vs. build date...do these add up? on: July 16, 2006, 11:07:57 AM
Huh?

The VIN range for 04C is N6366xx-N6277xx, about 8900 units.
1058  Camaro Research Group Discussion / General Discussion / Re: VIN vs. build date...do these add up? on: July 15, 2006, 04:10:33 PM
The dates & VIN ranges you have posted square with data I have had for over 20 years. At Norwood there was no 03A, 03C, 04A, 04B. There was an interruption in output there for some reason. Having worked in manufacturing my entire career I know that for a plant dedicated to a specific product all it is takes an outage of one component to shut it down.

The range of VINs for 02A is N602xxx-N615xxx, over 12,000 units. Probably depleted stock of everything.
1059  Camaro Research Group Discussion / Originality / Re: 1969 z/28 driveshaft on: July 15, 2006, 03:53:40 PM
For 1969 the driveshaft was common to all 1969 Camaros built with a Muncie 4-speed according to the P & A manual. 67 & 68 driveshafts are longer and do not interchange.

What they did in production may have been another issue. Z/28 driveshafts often have offset yokes while most others did not. They may have been balanced to a higher rpm.
1060  Camaro Research Group Discussion / Decoding/Numbers / Re: Brake Parts Numbers - 69Z - Rear Drums / Front Rotors on: July 13, 2006, 06:11:23 PM
Our 85,000 67 Z/28 had OE ball joints, drums and rotors. The rotors had never been turned and cleaned up with a light cut.
1061  Camaro Research Group Discussion / General Discussion / Re: corvette bronze code OO in 1968..how many made? on: July 06, 2006, 03:06:25 PM
Chevrolet never released production by color so there is no way to know how many of each was produced.

Our small db indicates about 6% of 1968 Camaro production was OO, not really rare.
1062  Camaro Research Group Discussion / Originality / Re: Camaro booster numbers on: July 04, 2006, 09:42:44 PM
Boosters are rated by output PSI at 20 and 100 lbs pedal pressure. In general disc boosters [so identified by "1-1/8 piston dia"] have higher PSI than drum.
1063  Camaro Research Group Discussion / Originality / Re: Original grill/bezel color? on: July 04, 2006, 09:00:29 AM
The headlight bezels should always match the grille.

If the car was Hugger Orange originally it would have to be an SS to have been built with a black grille. If it is not an SS the grille and bezels should be silver [aka argent].

1064  Camaro Research Group Discussion / Decoding/Numbers / Re: power brake booster code on: July 02, 2006, 10:01:10 AM
'0426' is the tab number for a 1970 Firebird with the HP option.
1065  Camaro Research Group Discussion / Originality / Re: Camaro booster numbers on: July 02, 2006, 09:58:23 AM
According to the Delco Moraine Service Manual dtd 1-70 '2945' is for a 1967 Pontiac Tempest with drum brakes. It has much higher output PSI than the Camaro unit.

A 1967 Camaro would use '0749' or '1109' with metallic brakes.

BTW these are the numbers on the tab, unrelated to the part number.
