Quadrajet Stage 2 Carb 66-73 GM Divorced Choke

The JET PERFORMANCE Quadrajet Stage 2 Carb 66-73 GM Divorced Choke is designed for classic muscle car and truck enthusiasts seeking reliable cold-start performance. This carburetor addresses the tuning needs of vintage GM powerplants, particularly those from 1966 to 1973, by providing a divorced choke configuration that enhances fuel delivery across varying temperatures.

The divorced choke mechanism allows for independent calibration of the air-fuel mixture, improving cold-start performance. JET PERFORMANCE has engineered this Stage 2 upgrade with tighter tolerances and recalibrated metering orifices, which can lead to better fuel atomization and combustion efficiency. This design helps eliminate thermal lag, which can cause hard starts and stumbling during warm-up cycles.

Restorers and street performance builders working with first-generation Camaros, Chevelles, Novas, and full-size Chevys will find this carburetor beneficial. Its OEM bolt-on specifications ensure that installation is straightforward, requiring no extensive modifications to stock mounting or linkage systems. This makes it an ideal choice for those looking to enhance their classic vehicles while maintaining compatibility with original designs.
