Frequently Asked Questions

The Holley Truck Avenger features a proprietary internal fuel metering block, a one-piece crossover fuel vent tube, and spring-loaded needle and seat assemblies. This setup prevents fuel spillover and float bounce on steep climbs up to 45 degrees, declination, and off-camber side hills.

The 670 CFM calibration is specifically optimized for small block V8 engines (such as 302, 350, 351, 360 cu. in.) and mild big block engines requiring strong low-to-mid range torque for off-road driving.

Holley carburetors require low pressure, ideally between 5 and 7 PSI. If your vehicle utilizes a high-pressure electric fuel pump or EFI conversion tank, a fuel pressure regulator must be installed to maintain proper operation.
