The Holley 4150C Truck Avenger, boasting a robust 670 CFM, is crafted specifically for those adventurous off-road applications. Its innovative fuel metering block is a game changer, effectively preventing fuel spillover through the boosters even at extreme angles. This means you can confidently tackle 40-degree climbs, navigate 30-degree side hills, and handle nose-down descents without the usual hiccups like hesitations, stalling, or flooding that often plague carburetors in rugged terrains.

This Truck Avenger is packed with features that make it a breeze to fine-tune your ride. It comes with a quick-change vacuum secondary system, four vacuum ports for all your necessary accessories, and a factory preset electric choke that ensures smooth startups every time. Plus, it includes a built-in fuel filter for added convenience.

Whether you're running a small block or a stock big block engine, this 670 CFM Off-Road Truck Avenger is the ideal carburetor to meet your needs.
