BBC Performer Manifold - w/EGR 87-90 454

The BBC Performer Manifold with EGR for 87-90 454 from EDELBROCK is purpose-built for big-block Chevrolet enthusiasts running fuel-injected 454 engines during the late 1980s model years. This cast-iron intake manifold bridges the gap between stock restrictive designs and full-race performance, offering a balanced platform for street and light competition builds. If you're upgrading a fourth-generation Corvette, Camaro, or truck-based 454, this manifold delivers improved flow characteristics while maintaining factory emissions compliance through integrated EGR provisions.

EDELBROCK's Performer series represents a proven middle ground in intake design—engineered for better velocity and distribution than OEM castings without requiring custom fuel system modifications. The manifold's internal passages are optimized for 454 cylinder head ports, promoting even fuel charge distribution across all eight cylinders and reducing hot spots that cause detonation. The retained EGR system integration ensures compatibility with 87-90 vehicle emissions standards, making this a bolt-on solution that passes inspection while unlocking additional horsepower and torque in the mid-range RPM band where real-world driving happens.

This manifold fits 1987 through 1990 454 engines equipped with TPI (Tuned Port Injection) or L98-style fuel systems—making it ideal for restorers, weekend racers, and street performance builders. Installation requires no custom fabrication; all mounting provisions, EGR bosses, and coolant passages align with stock locations on fourth-gen big-blocks. At 23.48 pounds, it's a straightforward swap that delivers measurable gains in throttle response and highway acceleration without sacrificing driveability or emissions compliance.
