Waking Up A 460ci Ford V-8
Our Big Block 1979 Bronco had been running fine with the factory cast iron intake manifold, but with bigger tires in this truck's foreseeable future, the heavy and restrictive manifold was simply holding back the power the 460 could pump out. With less than 1,000 miles since its stock rebuild, we went to work removing the old carburetor and intake manifold to make room for its new Weiand Stealth intake manifold along with a Holley 770 CFM aluminum Truck Avenger carburetor and a Holley 14-inch Power Shot air cleaner. The teardown was straightforward and easy, you can easily perform this mod with a few simple hand tools, a drain pan, gasket sealant and adhesive.
After installing the Weiand Stealth high-rise dual-plane intake manifold and the Holley 770 CFM Truck Avenger carburetor as well as the Power Shot air cleaner, we felt a dramatic increase in throttle response. In fact, it's too fast off the line - good thing it is, because we'll need that power to spin bigger tires in the sloppy stuff. Needless to say, it was a fun shakedown run. We couldn't even take off at WOT because a light tap of the throttle would push the old fullsize truck down the road like a hopped-up muscle car. The Weiand Stealth intake builds power from 1,000 rpm to 6,800 rpm and when paired with the awesome off-road features that the Holley Truck Avenger offers, it will turn a mild-mannered truck into a screaming beast - all while still being able to climb a hill at 40 degrees without stalling - something we couldn't do before!
