Edelbrock part #2892 Super Victor II intake manifold is designed to work with modern high flowing 23-degree heads on large cubic inch applications. The runner area at the plenum is 25% larger than our Super Victor #2925, and the port exits are machine-matched for use with a Fel-Pro #1206 intake gasket. Out-of-the-box modern casting techniques create smooth, thin and extended divider walls for "out-of-the-box" performance. This intake is machined for 4150 style carburetors. Can be port matched up to #1207 (1.38" x 2.28"). The Edelbrock Super Victor II is a single-plane, high-rise intake designed for maximum race-winning power at higher engine speeds.
