I got much better performance and spent less cash by buying this carb and selling my beautiful 600 CFM to someone who could give it a good home on a bigger block. If I had kept the bigger carb and resized the ports and pump jet the venturi, which cannot be modified, would still have been too big for best fuel delivery to a 302, and I would have spent a lot of money buying and trying different port and jet sizes. A street 302's max RPM is 5,800 and a street volumetric efficiency is 80%, so that's 302x5,800x80%/3456 = a 405 CFM carburetor, making the 390 CFM the perfect size by formula. The formula is Carburetor CFM = Cubic Inches x max RPM x Volumetric Efficiency ÷ 3456. I talked to Holley and they said the ports and accelerator nozzle needed to be cut down, which would have improved performance some, but I discovered the formula for carburetor sizing, see, e.g. The plugs kept fouling, and the engine would stumble on acceleration. When I put my 302 in, I first put a on a Holley 600-cubic-feet-per-minute carb that was otherwise identical to this one. Carroll Shelby picked 'em for his Mustangs and he was right. Out of the box it had fabulous acceleration off the line, it had fabulous acceleration at higher speeds, it gave me a steady, low idle, it gave me no stumbles, and it gave me clean plugs. The 390 version of this carburetor has proved to be the perfect carb to get maximum performance of my stock, street 302 on a 66 Mustang.
