The new Holley-style carburetor that Quickfuel received NHRA certification for will work on the 1965 325HP 396, as it is the same size as the carb on the 1966 300HP 327 @ 1.562X1.562/1.250X1.313. I had spoken to the folks at Quickfuel to find out if they had made any plans to certify a smaller version for the 275/270HP, but there doesn't seem to be a big demand for that particular unit.
Oh well!
