SBC Chevy 350 400 Polished Dual Plane Air Gap Aluminum High Rise Intake Manifold

High Rise Dual Plane Polished Aluminum Intake Manifold

Chevy Small Block, 55-95

This is a new polished aluminum dual plane intake for small block Chevy. 1800 high rise design, big power over a wide RPM range. Has the open air area under the carb pad to help keep fuel mixture cool and improve power. Ideal for everyday to high performance street applications, will produce power in the lower RPM range and not kill your bottom end like a single plane would.

These intakes are produced from steel molds to reduce core shift, have all the major features found on the expensive ones such as 4 corner water outlets and nitrous bosses, and the best part - the price!

Intake works with 283-400 small blocks up to 1995. Includes special adapter bushings for the middle holes on the '87 to '95 heads. Does not fit the newer Vortec heads. For use with square bore style carbs. Provides standard bosses and tapped holes for street accessories such as A/C and alternator brackets. No provision for manual choke or exhaust crossover and are not EGR equipped.
