Introduction

The 1969 Camaro was chosen as the Official Pace Car for the 1969 running of the Indianapolis 500 and as the Official Car of the ‘500’ Festival. This was a repeat performance for Camaro since it had also been chosen as the 1967 Pace Car.

To help them stand out on the large expanse of track, the 1969 pace cars were designed to be visible: Dover White RS/SS convertibles with Hugger Orange Z28 style stripes and orange houndstooth cloth seats. All were equipped with the recently released fresh air hood (aka: cowl hood).
 

Indy Festival and Courtesy Cars

The pace car was announced to the media at a February press conference in Indianapolis, aided by a display vehicle that showed off the pace car colors. [1] Chevrolet supported the race by providing the actual pace car, a backup pace car, a pace car replica (with air conditioning, power top, and show car finish) to be presented to the winner of the race, and a fleet of courtesy and support vehicles. This fleet included an additional 130 pace car replicas, 16 Impala station wagons, 18 pickups, two Suburbans, and one van.

Forty-three pace car replicas, all SS350 automatics, were provided to the “500” Festival Committee for use in the Festival Parade and other events. One of these cars (#34, 9N609349) and a matched set of luggage were then presented to the Festival Queen. In the picture above, the two pacers and the winner's car are believed to be in the front row and the Festival cars (identified by the Festival sticker on the rear quarter panel) are lined up behind them.

Seven replicas were provided for use by Speedway officials, and five replicas were for USAC officials. The remaining 75 replicas were for the visiting press and VIP's. Most of these cars were 350 automatics but some had 396 engines and 4-speed manual transmissions. It is believed that all the pace cars at the track were built in February, 1969, and all were built at the Norwood plant. The VIN's of some of the pace cars that were at Indy were recorded by Dr. John Mansell who attended the race. His list of 55 pace car VIN’s was published in the United States Camaro Club magazine in 1992. The highest VIN he recorded was 9N610726.

 

The Real Pace Cars

The two cars built to actually pace the race, the pace car and the backup car, were both ordered with the L89 aluminum head 375 hp 396 engines, automatic transmissions, power steering, sport-styled steering wheels, consoles, gauges, and AM radios. After assembly, they were shipped from the Norwood plant to the GM Tech Center.

Both cars were then identically prepared by Chevrolet Engineering and Chevrolet Experimental Department. The engines and transmissions were disassembled, thoroughly inspected, and reassembled. The aluminum heads were replaced with L78 cast iron heads, a special 6-bolt COPO torque converter was installed, and service JL8 four-wheel disc brake axles with 3.31 gears were installed. (The cars were not ordered with JL8, possibly due to limited JL8 availability.)

The driveshaft was balanced and the front JL8 brake components were installed. All chassis safety items and suspension components were magnafluxed/inspected and treated to insure they would not fail at the race. The heavy-duty battery and a 63-amp alternator were used to ensure 12 volts at all times (it is unclear whether the cars were ordered with these items or retrofitted). Prestretched drive belts were used and ‘aircraft-type’ hose clamps were installed on all hoses. 15-inch rally wheels replaced the standard 14-inch wheels. One car was equipped with Firestone tires and the other with Goodyear tires to give both companies equal promotional time.

Several external and internal body modifications were made for the pace car duties. Grab handles for the passengers were installed and flag brackets were mounted on the rear bumper. A two-way radio was installed to communicate with the tower. Hood pins and special convertible top boot fasteners were used to keep things in place at the 130 mph pace speeds.

The pace cars were driven by Jim Rathmann, winner of the 1960 Indy 500. Both pace cars were used to pace the race. The #1 car was used for the initial pace lap. The #2 car was used when the pace lap was rerun due to an accident. Both cars still survive.  

The Pace Car Replicas

Replicas of the pace cars were also white RS/SS convertibles with white tops ordered under RPO Z11. The Z11 option was announced in the February 4, 1969 Product Bulletin. Chevrolet also stated that “...we plan to build replicas of the Pace Car to be sent to nearly all of the 6400 Chevrolet dealers across the country”. Actual production was 3,675 cars; this number includes the Camaros that were provided as courtesy and track vehicles at the race.

The Z11 option was listed on the window sticker as 'Indy 500 Pace Car Accents' for $36.90. The SS side stripes were replaced with the orange Z28 hood and deck lid stripes. (The pace cars and the Z10's were the only non-Z28 models to use those stripes.) The Z11 package added orange D96 fender striping (not normally painted on Z28's), and also added white rocker panels (normally blacked-out on SS cars), and white rear tailpanels on the SS396 cars (normally blacked-out on big-block tailpans). Door decals were included and were shipped in the trunk; installation was at the discretion of the owner.

The required options with the Z11 package included C05 white convertible top, D80 spoilers, YA1 deluxe seatbelts, ZJ7 rally wheels, ZL2 special ducted hood, Z22 Rally Sport, Z27 Super Sport, and Z87 custom interior (orange houndstooth, code 720). Cloth seats were not otherwise available in a convertible.

The base drivetrain was the SS350 with a 3-speed manual transmission. Any other option could be added, including 396 engines and optional transmissions. Most cars were ordered with an optional transmission, most commonly a 4-speed manual or a 3-speed automatic (though both 3-speed manual and 2-speed automatic pace cars do exist).

Note that console and gauges were optional, thus automatic cars can be column shift. Deluxe front shoulder seatbelts (RPO YA3) were not required, but are a somewhat common option on pace cars. Over 40% of the pace cars exported to Canada had the YA3 option [2] , though only 922 convertibles had them in 69. Power convertible top is another common pace car option. No documented pace car has been found with JL8 four wheel disc brakes, though a few have had the JL8 brakes added by owners.

There is no documentation of the number of big block pace cars that were produced. The author estimates the percentage of 396 pace cars as between 15-20%, or approximately 550 to 735 cars. Several sources were used for this estimate. CRG’s database (though not a random sampling) contains data on over 7% of the 69 pace cars and about 19% of these cars are 396 cars. Furthermore, 20% of the pacers exported to Canada were big blocks. [2] For reference, 38% of all 69 SS Camaros were equipped with 396 engines.

Pace cars were a bold color combination and were expensive -- at least $3700 for the basic 3-speed manual car (and most pace cars were ordered with more options, such as an optional transmission for ~$200, power steering for $95, etc.). This resulted in some cars sitting on dealer’s lots for months; one sat for 9 months! On the other hand, some cars were purchased the day they showed up at the dealer.

 

ID'ing

Pacer interior
The pace car replicas were built at both Norwood, OH, and Los Angeles, CA assembly plants. Analysis of the CRG database indicates that about 85% (~3125) of the pace cars were from Norwood and 15% (~550) were from Los Angeles, which compares well with the overall plant production volume ratios. [3] All pace cars are RS/SS convertibles and will have 50-A paint and 720 interior noted on the cowl tag; they were the only Camaros built in this color combination. The Norwood cars will also have Z11 stamped on the cowl tag. The LA cars were not stamped with Z11 on the tag, but the colors codes on the tag confirm that it is a pace car since no other Camaro convertible received houndstooth interior. The pace cars were all built between 02D (4th week of February) and 05A (1st week of May).

For specific ID features, reference the 1969 ID Table. Since a pace car must be an SS, it should have 2 fuel lines (indicating a Rochester carburetor) unless the car had the L78 396 engine. If a pace car is missing its original engine, it can be difficult to determine if it originally was a small block car or a big block car. As noted above, not all cars have consoles and gauges. It's not uncommon to find column shift automatics and console-less 4-speeds. Pacer ad

 

Z10!

It was a well kept secret for a number of years. The pace car convertibles had a sibling!

There were a limited number of RS/SS coupes built via the option code Z10 that received the pace car style orange Z28 striping, essentially coupe versions of the pace car. Paperwork documenting why the cars were made has not been found, but they were sold in the Southwest area of TX, OK, NM, LA, and AZ (and at least two Z10's were sold new in western TN). The option was somehow communicated to dealers in these states (probably via zone letter) and the dealers then placed their orders (Chevrolet did not build cars without a dealer or customer order). Production records have not been found; however, using CRG's data on known Z10's, Z10 production is estimated to be about 400 to 500 cars. (There were at minimum 350 Z10 cars; the estimate will become more refined with more data. Yes, this estimate is higher than other prior estimates, but the data supports it.)

Z10

All Z10's are RS/SS’s, painted Dover white (code 50) with white rocker panels. SS396 cars had white tailpanels. Required options for the Z10 package were D80 spoilers, ZJ7 rally wheels, ZL2 special ducted hood, Z22 Rally Sport, and Z27 Super Sport.

The Z10’s were built at Norwood and Z10 was stamped on the cowl tag. All the cars were built between the third week of April (04C) and the first week of May (05A). No Los Angeles-built Z10's have ever been found and since LA was in the midst of a strike when most Z10's were built, it's very doubtful any were made there.

Five different interiors have been observed in Z10's. Approximately half of the cars received the ivory standard (code 727) interior. The other four interiors seen in Z10 cars are: black standard (711), black deluxe (712), black houndstooth (713), and ivory houndstooth (729). There's no evidence that any Z10’s were built with the orange houndstooth interior found in the pace cars.

Most Z10’s have the L48 350/300 hp engine, but the 396 engines were optional. Most of the cars that did have the 396 were equipped with the L35 325hp engine, though there were a few L78 396/375 hp Z10’s. The 3-speed manual transmission was the base transmission, but, like most SS cars, most Z10's were optioned with an automatic or a 4-speed manual. About half of the known Z10’s are manual and half are automatics. The Z10 was available with any other 69 Camaro option. A large percentage of Z10’s have air conditioning and several cars with vinyl tops have been found.

Pacer and Z10

The Z10's were not at the 1969 Indy 500 race. Although they are sometimes referred to as ‘pace car coupes’, neither the Indy 500 race nor pace cars are referenced in any known Z10 documentation. RPO Z10 is shown on the window stickers as “Special Accent Striping” for $36.90; the same price as the Z11 option, but door decals were not included with the car. We do not know the reason for lack of reference to the Indy 500 in the known Z10 material, but we can speculate. Perhaps it was to avoid the Indy licensing fees, or perhaps there was a limitation in the Indy contract that restricted replicas to be convertibles. They definitely have a relationship to the pace cars, but until documentation is found, it’s all speculation as to why these coupes were built and then distributed in such a limited area.

(As a side note: The Z10 RPO code was used over the years for other special Chevrolet builds - e.g. the 1974 Spirit of America Nova, etc.)

You can help with the CRG's research on Z10's. If you own a Z10, please contact author and include a picture of the trim tag. Thanks!


Footnotes

[1]  Note that the display vehicle at the pace car press conference is not believed to be a pace car. The time is prior to the building of the first pace cars, it does not have any engine emblems on the fenders, and it has black rocker panels. It was probably a white car that was modified by Styling for prototype and promotional purposes. This same car also shows up in a few early promotional pictures.

[3] Norwood was producing about 83% of 69 Camaros at the time (adjusting for the early shut-down of the Van Nuys plant). As a percentage of total production, Norwood produced 87% of all 69 Camaros.
