The Edelbrock Performer Vortec intake manifold is based on the Performer 2101 and is designed for small‑block Chevy engines using 1996+ Vortec (L31) cast iron heads or Edelbrock E‑Tec aluminum heads. This dual‑plane intake improves midrange torque and throttle response from idle through 5,500 rpm, includes provisions for an external water bypass, and accepts square‑bore carburetors for street rod, marine, and engine‑swap applications.
