First, I want to thank this board for their help and wisdom, I have asked more of it than I've been able to provide in return. Hopefully some enjoy reading the blog authored in the build of my Camaro (http://www.rhoadescamaro.com/build
Presently I am trying to understand if Chevrolet or GM ever, since the Camaro started in 1967, provided a service manual, technical bulletin, memo, or any other kind of factory-authored document, authorizing or describing how a dealer's service department or owner, could change the metering jets (or any of the other common tuning elements like power valves, vacuum secondary springs, or accelerator pump components) in their first generation Camaro. Specifically I'm interested in the Z28 from 1967 and its Holley, but such documents, if they exist, might be much more broad and cover the entire Camaro line.
Some situations that might have warranted changes - a dealer operating in Denver, might have wanted to sell their cars with leaner than original jets? As leaded fuel began being phased out for unleaded, that too may have prompted some kind of manufacturer-authorized carburetor component change?
Basically, anything from the factory saying the owner could make carburetor component changes, for purposes other than racing. It could have been authored in the 60's, 70's, maybe even the 80's, which is ok, as long as it applies to the '67.
If something like this exists, it opens up a lot more tuning options for me, where I have to run a stock carburetor on my race car.
I've just about exhausted my Google-Fu, and in the past this place has been great at revealing info that exists nowhere else on the Internet...
Thanks so much!!
