BLEM - Weiand 8018 Stealth Intake Manifold for Big Block Chevy. Intake manifold appears to have been installed but it wasn't actually used on a running engine. There are a couple of spots with strange finish on the intake manifold and it was decided that it wouldn't be best to use this particular intake manifold on a brand new engine build (see close up photos). Engine Block Deck Height: Standard deck. Basic Operating RPM Range: Idle-6,800.
Intake Manifold Height: 5.250 in.
