FAQ
Do Vortec heads use a different intake manifold?
- Yes, Vortec heads often require a specific Vortec intake manifold. JEGS 555-513002 is designed for compatibility with 5.7 Vortec heads, optimizing performance.
What is a single vs dual intake manifold?
- Single and dual refer to the number of passages. Single suits high RPMs, while dual enhances low-end torque. JEGS 555-513002 offers optimal performance for carbureted engines.
What are the two types of intake manifolds?
- The two main types are single-plane and dual-plane. JEGS 555-513002, a dual-plane design, balances power across the RPM range for improved drivability and performance.
