Big Block GM Truck
JET Performance has released a Quadrajet carburetor for Chevy & GMC cars and trucks with 396ci and larger modified big block engines. The carburetor is extensively reworked by increasing main well size and is balanced to assure top end high RPM fuel flow. Several circuit modifications are made to keep the fuel curve correct throughout the entire RPM range and to keep consistent idle quality.
The carburetor is designed for modified big block motors with a dual plane intake manifold, headers, 8.5-9.5:1 compression ratio and mild ported or aftermarket heads. Recommended cam specs: Duration @ .050 min 210 degrees, max 240 degrees and a lobe separation angle of 110-114 degrees.
