Rules Verification for a Newbie

[Tony Corley]

As I've posted in other places on here, I recently purchased an older built GT/PA car that I'm just starting to go through and verify what I have. As far as carburetors are concerned, am I correct that as long as it is the same brand (Autolite 4100 in this case), and has the correct venturi and throttle plate sizes called for, manufacturer date code doesn't matter? In this case, my engine is a 1964 based 289, but the current carb is a C6 PF (1966 289 carb). Has the correct size centuries and throttle plates as the '64 should have. I know to some of you that have been doing this a long time, these questions probably seem silly. I would never consider cheating, but I would hate to show up at a race and be disqualified because I didn't fully understand the assignment. So thanks in advance for answering the dumb questions.

What you need to do is contact the tech department in Glendora. That's the ONLY opinion that counts. You "probably" have a carburetor you can use. Just get it in writing.

Then that's what I'll do. Thanks

The part # and codes on the carburetor have not
been a concern for many years now.

The specs on the other hand certainly still are
the concern.

This is what I thought, because the rulebook specifically states:"Replacement carburetors permitted provided they are
same model, type, throttle bore, and venturi size. "

What combo are you running? As a general statement, the Ford combo is the 1.08 carb and the Merc combo is the 1.12. More to it than that but that should at least get you started on figuring out what you need.
