Pontiac 350/400/455 800-CFM Stage 2 Quadrajet by JET Performance®

Stage 2 calibration targets modified Pontiac V8 street/strip combinations.

JET Performance® 32102 Streetmaster Stage 2 is an 800-CFM Rochester Quadrajet four-barrel for modified Pontiac 350, 400 and 455 V8 engines. It retains the core inspection, casting-plug sealing and renewed service parts of Stage 1, then adds revised idle, off-idle, primary, accelerator-pump and high-speed circuits for modified engine airflow requirements. Stage 2 is intended for engine combinations with intake and exhaust changes, mild cylinder-head work and camshafts around 210–220 degrees duration at .050-inch lift. Later-style linkage may require adaptation on earlier vehicles.
