Can't see the item via that link...... but I'm not a BookFacer.

I was curious as to what others thought of the finish on this carburetor, it seems to me that there is a noticeable variance in many of the yellow chromate ( I assume) finishes from one "restored" carburetor to another. This one being more faded and looks closer to several older carbs I have sitting around. What would a correct restored carb's finish be? Any pics?

Here's another one he's offering for a '68Z. States he has 10 more with different dates.

I'll post them for you Tim.

Here is the 68.

Here is a nice page showing the variations represenitive of different surface appearances.

Keep in mind when it comes to Chromate (Clear) and DiChromte (Yellow) conversions.

It is kind of like asking how Red is Red or How Glossy is Black (Tailpanels)
as to your question "I was curious as to what others thought of the finish on this carburetor"
for me personally I would rather see a bit more yellow or bronzy coloring but this seems VERY subjective and taste driven since the specs for post treatment were established for preservation of substrates given corrosion resistance as subjected to spray tests and not how it appeared.
I would agree in our pursuits of this hobby Looks Matter esp when spending levels are at such asking prices.

It is on the top of every forum page. "Classified ads are not allowed on the forum."
I'm leaving this one since it discusses the color issue.
Thanks!

I was also thinking they should be a little more yellow/goldish. It's been a while since I purchased a new Holley but I was thinking they were. The reason I was asking is I'm looking for a what I think would be a little hard to find date 4053, somewhere in the early to mid 11/67 range. I found one that the metering blocks, base plate and stampings look legit but I've seen so many variances in what I find with finishes.

Hi everyone. Those are my carburetors and the reason there that color is I wanted them to try and look more like the original Holleys. I remember the old Holley being more of a olive green color not that bright gold color that guys put on them. Harold Demes does the carbs and from he has said you can longer get the original cadmium dichromate to make that color. He has to do something different to get the color that I like.

Here's mine, done by Eric Jackson:

The real issue I always see with restored Holley carbs is the metering plates are always the same color as the rest of the carb. That's not the way they originally came. The carb body was a darker green than most people see and the metering plates were even lighter.
Here's a picture of my carb before it was restored. Notice the different colors. Body fairly dark, metering plates and vacuum can lighter and the base plate even lighter. Most "restored" cabs I see are all the same color!

Ed, That’s exactly how all of my original Holley carbs look.
-
I spoke to Harold about the color and he said that the goldish color will turn to that green with the heat and time. The difference of color between the bowls and metering block is the heat. Fuel keeps the bowls kooler so they don't turn as dark.Most people don't know that dychromate wasn't to color them but to stop them from rusting .
-
Well, that could be. After 60 years memories can play tricks on you, but like you, I too remember the old Holley carburetors being more of an olive green color than what we're currently seeing on the restored carbs.
