Pro Products Cyclone Dual Plane Manifold - SBC Idle-5,500 rpm
$115.95
The Cyclone Dual Plane Manifold is a direct replacement for the stock manifold on 1957-’95
Small Block Chevy non-EGR engines. Will NOT fit 92-97 LT1 reverse flow heads. Includes special
adapter bushings to fit ’87-’95 engines. Use the stock
Quadra-Jet carb or 500-650 cfm vacuum secondary
carburetor. Kit includes adapter plate to permit use
of certain square bore style carburetors. Power+Plus
Manifolds are cast from steel molds, not from sand
molds. Permanent molds provide a tighter grain casting,
thereby reducing the occurrence of porosity which can
mar the polished finish. Additionally, each Power+Plus
Manifold is 100% pressure tested for leaks to eliminate
installation problems. This is our most popular manifold
and is showing up on many performance street
machines and street rods.
