The Edelbrock Performer #2146 & #2515 intake manifolds will work with 400, 430, and 455 c.i.d. big-block Buick engines. The Performer #2146 is designed to accomodate original cold air induction hoods, while the B4B #2515 relocates the carb pad for optimal fuel distribution. These manifolds optimize performance for engines operating in the idle to 5500 rpm range. They are compatible with OEM carburetors that use a divorced-style or electric choke only; hot air tube models will need to have their choke converted to electric or disabled. These intake manifolds are recommended for street rods and street high performance applications. When used with any mix of aftermarket equipment designed for idle to 5500 rpm operation, the performance increases will be even greater.

• KIT CONTENTS: 1 – Square-bore carb adapter plate #2732 (#2146 only) 12 – 3/8” Flat washers for manifold bolts
• EMISSION SYSTEMS: These manifolds will not accept stock EGR (Exhaust Gas Recirculation) equipment or exhaust-heated chokes. EGR systems are used on most 1972 and later model vehicles. These manifolds are also not compatible with AIR (Air Injection Reactor) systems and the 5/16” holes must be plugged on 1972 and later cylinder heads. Check local laws for requirements. These manifolds are not legal for use on any emissions controlled vehicle where such equipment is required.
• ACCESSORIES & INSTALLATION ITEMS: Major recommendations are listed below. However, due to the variety of years, makes and models to be covered, please review each part listed in the Installation Items section of the Edelbrock catalog to decide whether more items are required for your specific vehicle than are mentioned in these instructions. See our catalog or website for details. To order a catalog, call (800) FUN-TEAM or see www.Edelbrock.com.
• CARBURETOR RECOMMENDATIONS: Performer manifolds #2146 & #2515 are intended for use with either an Edelbrock or an original equipment carburetor. Carburetor stud kit #8008 or #8024 can be used to mount either style of carburetor. When using an Edelbrock carburetor on Performer intake #2146, the square-bore adapter plate that is included in the box must be used between the intake and carburetor with a gasket on both sides. The B4B intake #2515 has been designed to accomodate both square-bore and spread-bore carburetors without an adapter. Please note that Edelbrock carburetors have no provision for an evaporative canister or for EGR.
• THROTTLE BRACKETS: Due to the design of these manifolds, the throttle and kickdown bracket on some vehicles may require modification to fit.
• GASKETS: These manifolds are compatible with facing piece gaskets, such as Edelbrock #7246, when used with the factory valley
pan, or with gaskets that have the pan integrated, such as Fel-Pro #MS96005 (1967-1971) or #MS96014 (1972-1976).
