Good To Know

Q: Why choose a dual plane intake over a single plane? A: A dual plane splits the plenum to preserve low and mid-range torque, which suits heavy street cars and trucks better than a single plane. Single plane manifolds favor high-rpm airflow instead.

Q: Will this manifold clear my hood and accessories? A: Manifold height and carburetor choice both affect hood clearance. Check the measured height against your engine bay before ordering, especially in older or lowered vehicles.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
