Nos carbs.

When you're unsure of the original specs, parts, or potential OEM application of a specific List Number Holley carburetor, you need the Holley Illustrated Parts & Specs Manual. Available as Holley part number 36-51-7, around 50 bucks from many popular locations (including the Big"A".

I'm sorry, mine's somewhere in storage boxes 500 miles away so I can't look them up for you.
PS If your doing online shopping and it seems like the seller "SuperShops" has lots of Holley 'Group' stuff available, that's because it's.....Holley.

Thanks the info and the lead on how to find them going forward.

Much appreciated

Also, from the Rule Book, Section 11A, page 3:
"CARBURETOR
Must be correct year, make, and model specified for car’s
engine; fuel or air bleed passages may be resized. Drilling idle
holes in primary throttle blades permitted. Other modifications
prohibited. Sandblasting, grinding, flash removal, dry film
coating, or any other modification to carburetors prohibited.
Replacement carburetors permitted provided they are
same model, type, throttle bore, and venturi size. Computer
carburetors use latest model non-computer carb for engine
application. " (Emphasis mine)

First part of that; Must be correct year, make, and model specified for car’s
engine; Year was eliminated years back. Model has been modified some. Example; Chevy's can now run a front fuel inlet Qjet instead of 90degree inlet as they came out with. Main thing they do now is measure butterflys, and Venturi's.
