Hi Randy,

Do you know the engine assembly date for your GT350?  That couold be a better starting reference point to compare to other cars.

Randy,
The original Holley carb on 6S923 (built Feb 66 at SA and it's original engine on Jan 4th 1966) is marked List 3259 and dated 581.

I could not get the block assembly date today but remember it was cast in late October. It must be common for a lot of cars in the 600 to 950 range to have a August 65 carb. They must have made a big run that August.  thanks for any help, Randy

The 3259 Holley carb dates seem to vary quite a bit. They are not as "precise" as other dates, like say a radiator, glass, or other parts that were installed on the car on the assembly line at Ford.

So, I would say that pretty much any date before the arrival at SA would be good. As suggested, 581 would be a good choice.

Hi Brant,  Would the 3259 carb been installed at the Cleveland engine plant, thus the carb date should proceed the engine assembly date.  Or was the carb installed at the San Jose plant and the carb date should proceed the San Jose build.  Or the Ford carb was installed to drive the cars onto the transport to SAI and the 3259 carbs were then swapped at Shelby American, then the carb date would proceed the SA dates.  Where the engines accessorized with fuel pump, fan blade and carb, etc. at San Jose?

Thanks

Cory

Excluding carry overs and the like the engines were shipped with Carbs in place but other items, fuel pump, pulleys, alternator....were installed at San Jose before the engines and trans were VINed and connected together
