    What was the original primary jet size for the 1967 GT 500 BK & BJ Holley carburetors? Mine have 66's in them and I believe them to be true originals. It would be nice to see what others may have.

    Any info is much appreciated.

    According to my Holley book both 2804 and 2805 should have #66 jets and #65 power valves.

    Thanks Tex,
    I thought so, good to know about the power valves too. I'm thinking of bumping the jetting up a little as I run a higher lift cam (0.562) with headers and MSD box. Its always good to know where the starting point is before experimenting.

    Thanks again,
