Holley Street Avenger Carburetor; 4 bbl; 670 cfm; is rated 4.0 out of 5 by 1.
Rated 4 out of 5 by from Nice carb, great price, some tuning might be needed Put this on my old GTO, to replace tired 800 DP Spreadbore that was on there. Likely some of the modifications / tuning I encountered, although easy, probably aren't something many will run into. Secondary linkage hit on manifold - had to grind away manifold to eliminate binding. Early 70's Torker, designed more for direct replacement using original Q Jet. Jetting seems close, but accelerator pump too small for my application. Went from .31 to .37 pump nozzle, appears .40 will be needed. So 50 cc pump conversion, hollow screw, and accelerator tuning kit will be needed. Probably results of 3500 stall convertor and 4.88 gears in the car. Holley might consider adding the larger pump, hollow screw, and a small tuning kit and instructions to the base model. Electric Choke seems to work great - will enjoy that vs. the old manual setup I had. So just be aware that drop on out of the box and go may depend on your application.
