The Edelbrock Performer EPS Vortec intake manifold fits small-block Chevrolet 262–400 V8s with Vortec or Edelbrock E‑Tec heads, using a dual-plane low-rise layout tuned for peak torque near 3,500 rpm on a 350ci engine. It delivers useful midrange power from off-idle to about 5,500 rpm, showed dyno torque gains in the 3,000–4,500 rpm band, and is designed to pair with a 4150-style square-bore carburetor for best results.
