    Thumbs up Holley Ultra Street Avenger Carburetors

    The Ultra Street Avenger Carburetors feature all aluminum construction and are equipped with metering blocks and a base plate made from 6061–T6 billet aluminum. Three different anodized color options (Red, Blue, or Black) allow for a personalized look while maintaining the ultra high strength and durability you get from billet. They Weigh in at approximately 5 lbs less than a comparable zinc carburetor.

    The new Ultra Street Avenger Carburetors have the same great features as their aluminum counterparts such as a tumble polished aluminum finish; quick change vacuum secondaries for easy tuning to optimize performance or fuel economy; four vacuum ports for all necessary vacuum accessories; factory preset “No trouble” electric choke for easy start ups; built–in fuel filters; and an included fuel line kit so there are no unnecessary trips back to the parts store. Ultra Street Avengers feature the same optimized street calibration as the zinc versions so you know they will run great on your vehicle. In addition, the Ultra Street Avenger now comes with anodized metering blocks and a base plate made from 6061–T6 billet aluminum and a built in, clear fuel level sight glass for easy, no mess fuel level adjustments.

    The clean, polished look coupled with Red, Blue, or Black metering blocks and throttle body will certainly set your ride apart whether you are at the show or track.

    Don't trust your performance to just anyone, Holley is the only Modular carburetor company that has been in business for over 100 years and has powered every NASCAR champion since the 60's.

    Default Street Avenger Ultra

    We've been driving a car for a month or so with a Street Avenger Ultra, and it's a really nice piece. The car starts clean, has great response, and makes power up top. It's easy to tune, although I think we can get better MPG with more tuning. All looks good so far.

    I would like to try one of these "new" Ultra Street Avengers but I need one in the 870 cfm size. Holley offers the "standard" Street Avenger in the 870 cfm size, why isn't there a 870 Ultra Street Avenger?
