Yesterday I called D&D Performance about my carburetor and they were able to help me find the perfect carb and gave me a decent quote on labor at one hour. The carb that I will be replacing the old one with is the Holley Model 4160 part number 0-80457s (take that down)...
...While an O'Reilly store a distance away happened to have mine in stock they are available at Summit and Jegs but difficult to find elsewhere off the shelf. This is because this version of the Holley 4160 is the "tumble polish" it is not zinc coated like the shiny, more popular, "Avenger" model. A word to the wise passed on to me from the mechanic: The shiny ones get hot and gum up the works. I'm not sure then why they're so popular other than folks like shiny things - but forget them! If you need a new carb do yourself a favor and take the time to find a "tumble polish." I dropped "Tebow" (the Bronco) off at D&D with my beautiful new Holley, "Tebow" should be home on Friday. I must remember to call the mechanic tomorrow so he holds on to the old carb, I'd like to try rebuilding it when I've got free time. Oh and the man's opinion on Edelbrock: they're crap in high altitudes. I know others disagree, but I thought I'd share that too.
