Designed for Ford 429-460 street and high-performance applications with standard or Cobra Jet cylinder heads. The Air-Gap design features an open air space that separates the runners from the hot engine oil resulting in a cooler, denser charge for more power. This manifold is designed with a larger cross-sectional area (3.3 square inches) than Performer RPM 460 intake manifold #350-7166 for more gains with high-performance and large displacement engines. The carb mount flange accepts both square-bore and spread-bore carbs for Cobra Jet applications. Will not fit 1988 and later models.Installation Notes:
Hello, i have a stock 460 Ford with D3VE heads in my 21ft jet boat. Thinking of putting this on but right now my engine only recs to 4500 RPM. Will this help? If not will a larger flat tappet cam say 494 lift help? Looking for more all around power.
