Holley 3259 date
« on: June 10, 2022, 12:37:12 PM »
What would be the acceptable date code for Holley carbs on 66 GT350's in relation to build date at SA. Since they were installed at SA, there would have to be lag time for Holley to build, ship, inventory at SA, and wait to use up available stock. Late April build.

Thanks,
Tom

I asked this question of our resident experts a few years ago and was told that for my late March build, the acceptable Holley date range could be from later in 65 through March 66.

Looking at other cars there appears to be a group made and stamped 622 and 633
