SBC Small Block Fit For Chevrolet 262 265 267 283 302 305 307 327 350 400 V8 Engines Product Features: Haytalras 7501 Carburetor Intake Manifold small block is designed for Chevrolet 1955-86 262-400 c.i.d. V8 applications. It features improved technology and design that keeps the air/fuel mixture cool all the way to the cylinder heads. The open air space in the Air-Gap design separates the runners from the heat of the lifter valley cover, resulting in a cooler and denser charge for greater power. The runners have been tuned to raise the power band by 1,000 rpm compared to the original air-gap manifold—from idle-5,500 rpm to 1,500-6,500 rpm.
