So yes, this is the CV part.

Having a hard time with the idea that the punch numbers are floating all over one day but the next time this part was run the punch was straight?

Hi Scott,

A couple of comments...

1. I don't recall there ever being a underscore, just a space and your does have the space.

I was referring to the underscore in one of the pictures of the Holley in the link in your original post (see picture below).

5. Crooked lettering, hand set? l doubt completely. These were made in a factory making probably thousands a day. They did not have time to hand set each number. There might be an expert here that knows how they were stamped, but you have to figure that the date stamp was used for a week - all week. So a 6A1 carb, any Holley running down that line that week should have that same characteristic stamp. As I said from know examples, that 3370 is crooked beyond crooked.

What one has to do is get data, this applies to any part, once you have seen enough of them you can make a trend. 3370's I know and can compare known originals to the one I based this thread upon. Therefore the reason I did not want to base an opinion on a specific carb I have not studied.

Thanks for the reply, I understand (better) now. I am sure it would help me a lot, particularly during the reassembly phase, to look as many original examples of these cars as I can.

Clem:

Have I circled the 'dimple in the flat area' you describe above in the attached photo?

So, if I understand you correctly, 3370's on known original engines do NOT have this dimple, right?

...and the letters would stamped a little straighter, of course.

I really need to get out to events and see more original examples!

that is why i want someone to check an original because i know the later ones have the dimple BUT i don't know if the original ones do so we need some one with a old original to check and report back. might have to put that in the JG.

zzzzzzzzzz OK so I woke up to the question finally, yes, mine that has been safely boxed for 35 years has the dimple.

Re: Crooked is as crooks do - Holley 3370

anyone with a old original carb look and see if that little dimple is in the small flat area below the stamping. the reason i ask is later holley drilled and tapped this area for a emission setting needle that was sealed with putty. if this dimple is not in the earlier carbs this is a later model one holley sold without any stampings

Clem, I came across a pic I took of one of my two early service 396 carbs, and I noticed the dimple you mention. I also have a 3124 dated 874 with the dimples (also) on both sides, neither of which is drilled. Does this mean these carbs are typical of the 1966-mid 68 Holley production ?

in 69 or 70 holley installed adjustable needles in that area to fine tune idle emissions and then sealed the area with some type of putty. i will check some older holleys i have when i get a chance to see if they have the dimples.
