Legendary performance offering more value—Quick Fuel Street-Q carburetors deliver the power without the price. How? By retaining what's most important: the function. Street-Qs feature lightweight cast aluminum metering blocks and cast throttle bodies instead of billet components, so they cost less. But, the Q-Series performance remains: 2-circuit metering, down-leg boosters, changeable idle, high-speed air bleeds, and 4-corner idle. Plus, their universal throttle lever design accommodates Ford A/T kickdowns, 700-R4 bracket mounting holes, and the ability to mount brackets for Chrysler vehicles. Quick Fuel Street-Q carburetors fuel your passion and your budget with race-bred performance at no-frills pricing. Order the model designed for fitment on your vehicle application.
