I have a 67 coupe - with a Jan 67 L79, correct intake wrong carb.
What is the correct carb and does it have to be a Jan date?
There is a A.I.R California carb listed at Crane, but I do not understand the differences or can tell what to look for.
Zone 22 Dealer 151 - think this is a southern car KY, cant find dealer number, so its not a Ca car.

I can post the numbers on the Holley on it now, but it is definately not the correct one.

If someone has the correct carb I would WTB

Thanks

Correct Holley for 67 AIR emissions is R3814A. Carbs were installed at the assembly plant so a carb dated 6 months prior to the cars DOB would be correct. Typical date is 3- 5 weeks prior to assembly date.Something like a 6A3 or 6B1 date would be ideal.

Dealer numbers are in alphabetical order in each zone. Dealer 151 should start with the letter C in the southern KY area.

Non-A.I.R. 67's (both 300hp and 350hp) used a Holley 3810.

Current reproduction of the Holley #3810 is still available today. Made by Holley.....minor differences from original. If you are not concerned with numbers and dates, this is the one to buy. Available from a number of sources including "thepartsladi" on E-bay stores.

If you want a correct numbers match original, then be sure to get one from a reputable rebuilder or have someone "very good" rebuild it so that it will perform correctly. To many folks buy the numbers, but get a carb that won't run correctly. We can help with rebuilders names if you go this way.

You will be okay with a Oct, Nov, or Dec 1966 date, or an early Jan 1967 date. Check E-bay or Cranes Corvettes or Chicago Corvette for a good carb/core. Not certain a "restored" carb from Chicago Corvette will be trouble free.....may need more attention than they initially provided.

Proceed with caution when buying any 42 year old carb.

Thanks for all the inputs, currently I am leaning towards numbers correct so I will look for a rebuilt 3810 in Carlisle.
However Larry you make an excellent point, I do like to drive the car so I think I will go for a new 3810 and will follow your ebay link.

Donald - looking at the Crane R3814 I just don't know what to look for other than numbers that indicate its an A.I.R. carb - is that all there is to it? the numbers? bottom line I need to get a 3810.

Also thanks for the information on the dealer zone numbers, so do I start a business search for dealers in southern Kentucky? How would I know they have the 151 number?

Would the GM number 3906635-OP indicate that a 3814 was original? and was such a carb used as late as 1971?
Thanks!
