Designed specifically for small and big block standard deck Chevy V8s, this unit replaces and upgrades the stock High Energy Ignition distributor found in 87-93 car and 87-95 truck external coil applications. Features a machined finished base for an accurate fit and a show car appearance. Includes cap with brass terminals for improved conductivity, rotor and a high-RPM control module. We recommend JEGS 49K volt coil, 555-40110 (sold separately), to compliment your new high performance distributor. Will not fit LT1 or LT4 applications.
