C2 correct carb date for Oct 65 L79

[Bob Psolka]

What would be correct date code for Holley 3367, car build is mid-Oct 65

How far in advance were the carbs manufactured before installed on the line?

Was there a differences in the Holley that made it particular for Corvette compared to other Chevys?

Same carb for 300 hp and 350 hp?

Any concern for fake date stamps? I've seen some with LIST 3367, some missing LIST

THANKS

3367 was correct for 66' corvette and other chev. applications.

Date code would be.

Year (6) Month (1-0 A Nov B=D) Week (1-5)

Application would be: 327 300/350

Bob,

To add to William's info, you should be looking for a 3 digit date code which preceeds your engine assembly date within 6 months. 501 would be the first week in October, 1965 and would be nice. I doubt that you'll find any preceeding 3 month's prior, as you car is early in the production year.

If it has a 4 digit date code, it is a replacement after 1972.

Yes, you should be on the lookout for a restamp, especially if someone is selling you a high priced restored 3367. 3139's and 3140's look almost identical to a 3367, as well as others, and have been known to be restamped for the price differential of $150, to $600 or more for an original dated car. And again, as your car is early in the production year, there will be less of them available with the right date code.

I can show you a 3139-1 next to your 3367, and if you didn't read the numbers you wouldn't know the difference.

I think the LIST was on all the originals, as well as the part number with the application code letters (the last two digits). I don't have the book in front of me right now as to the proper part number, maybe someone will chime in.

Check out E bay item 8043408639. There's a 2nd week Oct 65 for sale. Ask for pix of the horn and sides and post them here. You'll get all the info you'll need. You can get this one restored to new for around $400 I think. (I have no connection with this carb) The first 3367s were made in August 65 I believe. The first 3 months are extremely hard to find. Mine is a 591 for my late Sept car. Took a lot of looking.

You can see some pix of what looks like a correct carb to me on E-bay item 8043024948.

Thanks,

I saw those ebay carbs, also I've located one dated early September 3367, already rebuilt, which seems to be perfect. And maybe I can sell my double pumper to recoup some cost and help out somebody's chevelle

My over the counter double pumper which I had on my 67, a 1976 4776, is sitting on the shelf in the garage. If you check on ebay, they are not worth very much.

4777-2, maybe $150 on a lucky day

Re: C2 correct carb date for Oct 65 L79

Carb date before Engine assembly date before car assembly date....Car built Oct 65? Do you mean a 1965 Corvette built mid October 1964, with most likely an engine dated/assembled early October 64 and a engine casting of mid September as well as a carb stamp of early-mid September.

My research shows 6-12 weeks between carb to car assy. The differences are in the fuel bowls I think, make sure the fuel bowl numbers stamped on the undersides are correct, different primary and secondary I think, but check your JM, as well as the obvious GM p/n, List and date.

Not sure on the 300/350...I doubt it.

Fake stamps are a HUGE concern on any Holley...My advice is to buy the most complete undamaged nasty looking core you can find, like its been on a shelf forever and have Jerry Luck restore it. Call Restores to find out what to steer clear from, like warped bodies etc..

Buying a restored one on ebay...well who knows what like beneath that new plating....Caveat Emptor

Bob,

I had a double pumper on my 67/327/300 for nearly 30 years, they work pretty good. But last year I put this original 3810 on:


I bought it as a piece of junk on ebay (about $250) and then spent about $300 restoring it myself.

Actually, the original carbs, adjusted just right, run much better then the double pumpers.
