The ultimate in Quadrajet performance.
JET Streetmaster Quadrajets Stage 3 carbs are intended for serious street/strip and race applications such as Circle Track, NHRA Stock, and Super Stock classes. They have all of the features of the Stage 1 and 2 versions, plus an oversized .149 in. needle and seat assembly, and an increased and balanced main well size area to ensure proper top-end, high rpm fuel flow. Extensive circuit modifications are performed to keep the fuel curve correct throughout the rpm range, and to obtain clean idle quality and instant off-the-line response for consistent race-winning performance.
