Anyone ever heard of a Holley 4021 carb? It looks like it's in the 4010/4011 family, but I can't find anything on a 4021.

If you have heard of it, what are the specs and pros & cons compared to a 3310.

I just checked the Holley site and they don't list a 4021. http://www.holley.com/HiOctn/ProdLine/CarbList.pdf
You'll need to click on the magnifying glass in the tool bar and then click 3 or 4 times on the page to make this readable.

I checked the Holley site too. The thing is, unless I'm not looking in the right place, that's the only number I can find on the carb.

The number should be on the right front of the choke horn. They don't show my carb on that site either, (4779-8). Since my carb is less than a year old I just assumed the site isn't totally up to date. You might ask Holley at the on-line help section. I've used it before and the response took a few days, and it wasn't complete. But maybe you'll have better luck.
