Chevy sent a Product Bulletin to dealers dated February 4, 1969 introducing the Z11 option. Unfortunately typical of them, all it did was create confusion. It states:
RPO Z11 is comprised of:
Camaro SS RPO Z27 with Rally Sport equipment RPO Z22
Custom Interior RPO Z87
Air Induction Hood RPO ZL2
Rally Wheel, Hub Cap and Trim Ring RPO ZJ7
This implies all this will be included with the Z11 option. Then another confusing statement:
“To be identical with the actual pace car additional options are required.”
Turbo Hydra-Matic M40
Positraction Rear Axle G80
Power Steering N40
Power Top C06
Console D55
Special Instrumentation U17
AM Radio U63
Air Spoiler Front and Rear D80
Sport Styled Steering Wheel N34
Custom Deluxe Seat and Front Shoulder Belts YA1
Soft-Ray Tinted Glass A01
“Required” implies just that-the equipment had to be ordered putting the MSRP at about $4300. However it does not mention the L78 engine or JL8 brakes the track cars had. Also makes no mention of requiring a white convertible top. As many Z11s were built without some of these options there may be a later version of the bulletin that clarified what was included with Z11 and what was required.
Here's what was ultimately required with Z11:
http://www.camaros.org/69pacer.shtmlI did an unofficial analysis of our db and came up with the following power train percentages:
L48 auto - 56.7
L48 manual - 21.2
396 auto - 8.0
396 manual - 14.1
This does not imply a 396 auto was the rarest combo. May be an L48 or 396 with the standard HD 3-speed manual trans. I've never seen one.
