Worked on Holleys for years on the street. I will not have one, except to sell. Always working on it, never quite right. Any 4 other barrel is better for the street. My brother had a Holley on his 65 Mustang 289 K motor that was messing up, so I put a MOPAR Carter AVS on it while I rebuilt the Holley. When I was done rebuilding the Holley, he told me to sell the Holley, because he was keeping the AVS. It ran so much better. Sold all my Holley "tuning" parts years ago, now I never have to "dork" with a Holley again. A friend of mine Just pulled all the Holleys from his street cars and replaced them with Edelbrocks after his twin brother had a beautiful 55 Chevy Restomod catch on fire from the Holley. Carters just flat out work.
For informational purposes, to change the fuel mixture with a Carter/Edelbrock, you just change rods. I does not get any better, faster or easier than that.
