Those large journal blocks should have 2482 on the center caps.

Al - Not questioning what you state, but I've heard for YEARS that because of the connections between GM and guys like Smokey Yunick, Truppi-Kling, Jere Stahl, etc., the headers were made by Stahl. How did you learn that they were made in Flint? That's new news and very interesting.

I hear 'ya. There a good chance that Bill Thomas Race Cars, Douglas as well as Stahl also made some of the headers for Chevrolet. When I worked in the parts dept. of our local Chevy dealer in 1972, there was a set of these GM part numbered Z-28 headers stuck way up on top of one of the parts bins. They were wired together along with a heavy manilla envelope that contained the header bolts, gaskets, and two sets of instructions....one from Chevrolet and the other from Kustom Headers.

Here's an link that provides some interesting history.

In 1967, you could order a Camaro with the fresh air induction system installed or as an accessory. You could also order headers that were "installed" in the back seat. If you ordered the fresh air induction as an accessory, it was "installed" in the trunk. You could also order a 1967 Camaro with no sound deadener and no heater. The cross ram was not released until sometime in the 1968 production year, after SCCA opened up the availability rules. By 1969 however due to SCCA lifting the rules, Fords had the inline Autolite carburetor parts for the Boss 302 and AMC had a cross ram 2x4 manifold and headers also.

The fresh air induction system you speak of. Are you talking about the cowl induction air cleaner/hood, or the wrap around fresh air sheet metal ductwork that runs over into where the heater used to be( like on Wenzel's car) ? I always wondered if that was a factory item or not ...

Wenzel's car is a 67. The wrap around air breather was an option, 7,8 & 9, dealer installed. GM sent a sketch to layout the location to cut the cowl / firewall. 7 & 8's only came with a flat hood.

I have a 69' built in Norwood,Ohio with the L89 option. But the aluminum heads on it are the 074 like they put on the ZL1 Camaro's.
