I recently acquired some original parts to our 66 Shelby. This carb was with the parts and was on the car back in the late 90s. It is an assembly line installed 3259 unit. This would be correct for a 67 Shelby small block with a 4 speed. It is dated 721 which translates to February, first week of 1967. Has the correct primary metering block 4756 and secondary 4560. The only thing wrong that I'm aware of, is it is missing the choke blade and pivot for some reason( I am by no means a Holley or Shelby fan expert though). Car was in California and probably wasn't really needed at the time.
Asking $4100
