I have heard many positive comments about the Holley HP carburetor series since their introduction. The whole reason Holley developed that line of carburetors was to compete with the carburetor tuners, and with Barry Grant. The HP carbs offer a viable choice to both.
The Holley list #0-82750 is a 750 CFM Four Barrel HP Carburetor, it is a Model 4150 with secondary metering blocks and center hung fuel bowls; it has Vacuum Secondaries; a "street" fuel/air calibration; Contoured Main Body; No Choke.
