Thermo-Quad ID

Hey all,

My '73 Cuda was born on April 4, 1973. I finally got my hands on the purported "Correct original" Thermo-quad. What numbers am I looking for, if any, to verify this?

Thanks,

Kansan

I've got a 6340 which is 1973 340 California auto trans only car and should be confirmation that it is an original California car. Until now, I could only confirm it was it was registered (pink slip) in California expiring in 1977 and a transmission rebuild receipt from AAA Transmission in Roseville, CA on 10-06-2005.

Thanks for the info as I trace the history of my Cuda. It was registered in Tennessee in 2007, and it came to Arkansas in 2008, according to the guy I bought it from. He said he never drove it in the rain while he owned it.

You have identified the carburetor application by number. To determine the build date, use the following:

1972 and later: The date code is stamped under the model number: The 1972 and later date code is in the following format: DDD Y Where DDD is the Julian Calendar number for the day of the year and Y is the last digit of the year. Example: "268 4" is the 268th day of 1974 or September 25, 1974. This code could also reflect the 268th day of 1984 or September 24, 1984. Thermo-Quad production was from 1969 through 1984, so date code years will be within this range. The model number differentiates which possible year date code is valid for that particular Thermo-Quad.

That is some good information, Vaanth... the date is 078 3 which equates to March 19, 1973...it aligns...I haven't used a Julian calendar since I retired from the military in 2007....gotta knock the fuzz off...


Thank you,
