According to the holley carb list from the official site, there's no such thing as a 7974. you sure you got those numbers right?

Check the Holley Carb Numerical Listing >> http://www.holley.com/data/TechServi...%20Listing.pdf

Thanks for the response. I couldnt find it on the site either, but these numbers are clearly located on the front of the choke housing...just like any other Holley. I want to sell it but not sure what size it is, has Vac Sec.

that would be a 600cfm vac and was actually a ford usa factory oem carb, that is why the number is not listed in holley listings. they have different fuel metering calibration to std 600's as per ford spec and work well. cheers
