High-velocity runners deliver excellent throttle response throughout the power band. The great looks of the Performer Air-Gap along with the solid idle to 5500 rpm performance makes this an ideal choice for street rods and street machines. Fits spread-bore or square-bore carburetors. Will not fit under stock Corvette hood.
