Streetmaster Rochester Quadrajet 4- bbl

STAGE 1 - Disassembled, cleaned and inspected to restore factory stock performance. Casting plugs are sealed with epoxy to prevent leak-down. All of the circuits are checked for proper sizing and the calibration is checked for proper jets, primary metering rods and secondary metering rods. Quadrajet Carb is reassembled with new float, choke pull-off and bronze bushed throttle shafts.

STAGE 2 - All features of Stage 1 carbs plus fully recalibrated idle, off idle, main, accelerator pump and high speed circuits. Provides improved idle quality, instant throttle response and maximum torque and hp.

STAGE 3 - For serious street-strip and race applications such as circle/oval track and NHRA Stock and Super Stock classes. Fully modified Quadrajet with oversized .149 needle and seat assembly. Main well size is increased and balanced to assure proper top end, high RPM fuel flow. Extensive circuit modifications are performed to keep the fuel curve correct throughout the RPM range, clean idle quality, and instant off the line response.
