Rules Verification for a Newbie

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.

It's currently set up as the Ford combo with a 1.08 Autolite. Just not the date code, part number listed for the '64. The carb I have is listed for the '66, with the same specs that the '64 calls for. I also have another carb that needs to be built that is listed for the '64 combo, but it's listed as a manual carb (my car is an auto) As far as I can tell, there is no difference in the venturi size or throttle blade size from the 2 carbs I have compared to the one the combo lists. Everywhere else in the rulebook (heads, pistons, rods, crank, etc, it)specifies NHRA Listed replacement. The carb is the only rule that states that a replacement is allowed as long as it is the same type, venturi size, throttle blade size, etc, which makes me think it's ok. I was just curious if anyone else had already dealt with this that could shed some light. I can do as suggested above, and contact Glendora.

Just make sure you have the correct bores on venturi and throttle blade. The date code, etc isn't an issue, just make sure you have the correct casting with the 1.08 or 1.12 ID on the bowl. For the most part the 1.12 Merc combos have been pretty beat up, most all of the cars you will find are running the 1.08 Ford combo in either SS or GT classes. People are also running the '68 Merc 302 with the Holley carb. It seems like the most preferable combo at the moment is the '64 Ford 1.08 carb combo.

Since this is a "get my feet wet in Super Stock" type of deal,and an older build, I'm just going to run it in it's current form. I'm just trying to go through it and make certain everything is still legal. I'll have the engine apart in the next few weeks. Then I'll be able to verify everything internally is still legal. As long as it is ( or can be made legal under current rules without spending thousands of dollars), then I want to give SS a shot. Otherwise, I'm just going to bracket race it. Ether way, we'll have a lot of fun.

Dude, You're over-thinking this, IMO.
Sounds counter productive to tear it apart and eye- ball the parts. If you go that far, it makes sense to at least hone and ring it. Same for timing chain, bearings and other wear items.
Instead, I suggest doing an external check of things..Leak down, compression check, check seat pressure of the springs, cut the filter open, etc.
If it looks okay , put some fresh plugs and oil in it. Take it to the track and see if runs the index, before you dump a bunch of money into it.
Where do you plan on racing it? Combos ? Divs? Opens? Believe me, nobody cares about the "legality" of another Fox body that runs a few tenths under.
The only place you'd ever get torn down is at Indy. Trust me..you ain't ready for that scene.
Again ,IMO ,and I've been doing this for more than a few years ;-)

I think he's just like me, want to get into it but am concerned I'll be illegal or do some obvious faux pas without knowing it.

"overthinking it" DEFINATELY fits me!!

As I've already stated in my build thread, I'm going to pull it apart and hone it, new rings and bearings, valve job, new springs, etc. I'll cc the heads, verify stroke and rod length, and run the cam through the Cam Doctor and make sure what it is. Also go through the trans and rearend, just to be sure. And lastly, going to bring the rear suspension into this decade. The engine was built in 2014, I want to verify condition of everything as much as legality. I think it will be 2 weeks well spent, and I would do that even if I was only going to bracket race it. Last year the car was brought out for test and tune. Supposedly was at legal weight, on old slicks, and ran .6 under GT/PA index. We'll see, soon enough. This isn't my first foray into drag racing, just first time into Stock/ Super Stock. I grew up with my Dad building and racing legal gassers. My first drag car was a B/MC VW bug, when that class still existed under the modified/gas umbrella, and they ran NHRA classes locally on a weekly basis,before bracket racing took over. Been involved in everything from NMRA heads up stuff to Pro Mod since then. But my local heros were guys like Mike Saye, Bill Howell, Everett Keesley, Ronnie Courtney, Boobie Hornaday, etc., and I've always wanted to run a Stocker, or Super Stocker because of them. I'm just trying to get a handle on how the rules are interpreted, from people like you that have been running the class for awhile. Thanks
