1967 Chevy Camaro Z 28 Options and Cowl Tag

Just in case there are skeptics, here's a shot of the cowl tag. The 4L designation that indicates the Z/28 option is at about the 7 o'clock position.

This is a shot of the block stamping that shows the MP designation indicating this engine came with an AIR pump as required for California in 1967. If the Z/28 had been a 49-state car, the block would be stamped with an MO designation. The famous DZ code is for '69 Z/28s

Here's what that factory traction bar looks like. This is the square, second-design bar while the first-design bar was round. Since my car was built in March, that must make the first design somewhat rare.

The Z/28 Option

The whole reason the Z/28 was created was to compete with the Fords and Mopars in the SCCA Trans-Am series. The over 2.0L class limited displacement to 5.0 liters, or 305 ci. Since Chevy didn't have a 5.0L engine, it responded in classic car crafter fashion by building a 302ci engine using a small-journal 327 4.00-inch-bore block and a forged-steel 3.00-inch-stroke 283 crankshaft. The cam was the classic Duntov 30-30 mechanical lifter camshaft along with a set of 462 iron 2.02/1.60-inch valve heads, an aluminum dual-plane intake manifold, and a Holley carburetor.

Since this was a road race car, Chevy bolted on a set of RPO J52 four-piston disc brake calipers and then specified a set of 15 x 6-inch Rally wheels mounted with 7.35 x 15-inch tires. A Muncie four-speed was the only transmission available (close ratio was standard, wide ratio was optional) along with a standard 3.73:1 rear gear and a factory-installed traction bar. This was back in the day when you could also get as deep as a 4.88:1 gear straight off the factory order form. The minimal Z/28 package in 1967 was the engine, four-speed, a 3.73:1-geared 12-bolt, and power disc brakes. Other options such as the RS package, headers, cowl induction, an air cleaner, a vinyl top, the spoiler package, and tach and gauges were available. My car did have a few options, including a tinted windshield, a console, and Positraction, along with a radio and a heater.

Everyone knows there were only 602 of these cars built in 1967. What I've never uncovered (not that I've looked very hard) is the number of Z/28s delivered for sale with the California emissions package. This has to reduce the number down to perhaps a few dozen at most.

This is the guy (whose name I don't recall) we purchased the car from in 1979. Mary told him it was a Z/28 and he didn't believe her, a mistake that was to pay off in my favor.

Here's the interior as it appears today. I've removed the B&M Quicksilver shifter that replaced the one the car came with when we bought it. B&M did the installation and cut the chunk out of the console, which means I'm going to need a replacement.

This is the '67 Z/28 PR car in a hard right-hander. Note how that left front tire is folded under. Despite its performance image, these cars handled very poorly in stock trim.

This is what a stone-stock Z/28 engine looked like with a cowl-induction air cleaner. Note the deep-groove alternator pulley matched up with a deep-groove water pump and crank pulleys. This engine was also equipped with factory headers that were unique with four-bolt flanged collectors.

Among my little photo treasures is this shot of what is either a '67 or '68 Z/28 with the cowl-induction air cleaner for a cross-ram.
