I very much look forward to new reports. Good job Ed and Thanks CRG!

Thanks, Ed, for all your hard work on the report.  Those pics are a very good reference source.  This type of technical information is why so many 1st gen Camaro enthusiasts frequent this site.  Keep it up CRG

Thank you very much guys, but I have to admit, I was really only the conduit here! Jerry, Kurt, John, Troy, Greg... Everyone contributed to the article be it pictures, HUGE amounts of information, formatting assistance, help with the actual construction, etc...

Although everyone joined in, Jerry was instrumental in supplying a lot of the Holley information. He really knows his stuff!!

I could never have even finished if it weren't for Kurt! I can't tell you how many time I read and re-read this thing, and Kurt STILL found errors!!! He also gave me great direction in HTML, of which I'm VERY weak!!

Troy and Greg sent me some great pictures, and like Paul said, pictures are worth 1k words.

John, Bill, Martin, Rich... EVERYONE assisted in some fashon, so that's why I insisted we put the "CRG" in addition to my name as the author.

And of course, the article will never be "done". Heck, Richard (rich69rs) just sent me some great info on the Rochester two barrels! I'm looking at incorporating that into the article as well. It's surprising the lack of info on 2GV's!!

Excellent report!  Thanks for taking the lead and putting in the effort that it takes to produce these things Ed.  Thanks too to all those other CRG members who helped make the final product so good.  These reports are a fundamental part what makes CRG so unique and such a valuable resource to the Camaro community.

Ed, I've got a 69 307 2 bbl. I can't swear to originality, but If you want me to check something or photos, let me know. The carb will probably be coming off this summer, I'm planning to go with a TPI system.

Thanks,

Hi Ed -

Quote from your carburetor report...

"In 1952, a new 250,000-square-foot manufacturing plant was opened in Bowling Green, Kentucky, and product development continued with the first Holley modular carburetor, the model 4150 that was made standard on the 1957 Ford Thunderbird."

In case your interested and need any info, my dad purchased a 1957 T-bird new.  I saved (inherited) a garage full of parts to this car (sold when I was born) that my mom was going to dump.  Among the hundreds of parts I have is the original Holley 4-barrel carburetor.  Some numbers off the carb...

L/H side of air horn stamped:  743  (date code)

R/H side of air horn stamped:  ECZ  AD
                                            LIST-1273-1

Primary metering block stamped:  1584

Secondary metering block stamped:  1589

Venturi casting number:  6R 1269 B

Ed, if your interested in any other data from this carb, please let me know.  Thanks again for taking the time to write this report!  I found the history of the manufacturers very interesting.
