Edelbrock's intake can free up 8-12 horsepower on a stock 5.0, and up to 30 horsepower on an engine with performance cylinder heads! Edelbrock really does their homework. These manifolds feature the best air distribution (most even air flow from cylinder to cylinder) of any manifold we've seen. The removable plenum cover gives you direct access to the intake runners for easy porting and polishing.
The Performer 5.0 is your choice for most daily-driven street cars which need a lot of mid-range torque and horsepower below 6000 rpm.
The Performer RPM is perfect for high rpm when combined with a rev-extender. The Performer RPM's shorter runners are also a great match for the high airflow needs of stroker motors and 351 conversions.
