BLEM BluePrint Engines Dual Plane Intake Manifold for Vortec Small Block Chevy

  

BLEM - BluePrint Engines Dual Plane Intake Manifold for Vortec Small Block Chevy. New, unused item with visual defects. Intake manifolds have residue or oxidation on them from the machining fluid. They should still clean up okay (but not perfectly).

They also have 1 plug in the front water crossover that is too deep according to specs. This also should not affect functionality at all.

Engine Block Style: SBC Stock / OEM standard deck. Carburetor Mounting: 4-barrel square bore. Basic Operating RPM Range: Idle - 6,200. Intake Manifold Height: 4.595 in.

Features two 1/2" NPT plugs on top of the front water crossover, and one 3/8" NPT plug facing forward, perpendicular to the thermostat. The rear most 1/2 NPT pipe plug on the rear intake runner is for brake booster.

This is NOT a water port. This intake manifold features the Vortec (vertical intake bolt) Pattern.

This is the production intake manifold used on BluePrint SBC engines 400 CID and smaller. May not be compatible with OEM chokes, or OEM accessory mounting brackets.
