What Holley numbers are checked during judging

[Matt Malloy #42289]

I bought a 2818 Holley off of ebay to put on my 65 Coupe. I sent it to a carb restorer to get rebuilt and he called me and said I got ripped. He said the baseplate was for a Ford and one of the metering blocks was not correct. He sold me one he had in stock and sent both back to me. To me they look the same. I even measured everything and they check the same. They are both List 2818, one is dated 431 the other is 451. Do judges check numbers on metering blocks and baseplates as well? The only differance I see between the two is the ebay carb does have the wrong linkage arm where the throttle hooks up.

Metering blocks, maybe, but throttle arm configuration is a definate "gotcha" to anyone remotely familiar with a Chevrolet Holley, as are specific configurations of the baseplate.

I left my judging guide at my body shop. One metering block has 4099 and the other has 6946, with 63901 underneeth the 6496. Are these correct numbers?

Re: What Holley numbers are checked during judging

the 63901 is a 1972 IHC 392 cu in engine carb # and the 6496 is the metering for this carb. the holley parts book list metering body # for the 2818 as 134-129 and 134-130

Matt:

Here is how your numbers should look.

Primary block..............4094
Secondary block............4099

Air horn:

3849804

LIST 2818 (early)

LIST 2818 - 1 (after 11/64)

XYZ (x=year, y=month, z=week in month)

431 date........1964, 3rd month, 1st week of the month
451 date........1964, 5th month, 1st week of the month

The "431" date is too early for a 1965 engine. The "451" is AOK if your engine was assembled before about December 1964 (using the 6 month rule of thumb).
