Edelbrock part #7136 Pro-Flo XT EFI intake manifold is engineered for high performance 396-502 c.i.d. Chevy V8's with rectangular-port cylinder heads. A large plenum and tapered runners deliver maximum horsepower and broad torque throughout the rpm range (1500-6500 rpm). It features a 90mm throttle body opening for maximum performance. Aesthetics were also a major consideration in the design, offering enthusiasts a custom look. 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. Pro-Flo XT EFI intakes accept Edelbrock Pro-Flo XT Throttle Bodies and Fuel Rails (sold separately)..
