I have to buy a new Q-Jet Carb for my rig. The mechanic says that it won't pass emmissions with the one that's on there. I have a mostly stock 350 with headers and an Edelbrock intake manifold. A stock rebuild is about $230.00. The Jet Performance Products Stage 1 rebuilt is about $350.00. The stage 2 is about $360.00. The Edelbrock new Q-Jet is between $400.00 and $460.00 depending which one is right for my rig. The Blazer is a '74. It must pass the Phoenix emmissions test. I don't mind spending a little more money for extra performance if it's worth it, and will pass emmissions. I wan't to do it right the first time. My tags expired at the end of April so I have to decide quick. Please help!
