Description

The Holley CO63VSB-LS is a single-plane, split-design cast intake manifold for high-performance/racing applications. It's compatible with GM LS Gen III engines with cathedral port cylinder heads and accepts 4150-style square bore flanged carburetors or throttle body EFI systems. The split-design aids custom porting and reassembly with shoulder bolt locators and O-ring seals. It offers optimal performance in the 6000-7000 RPM range, features a race-bred design, lighter weight, captured O-ring seals at head ports and split, and multiple vacuum port options (2x 1/8", 1x 1/4", 1x 3/8" NPT).
