Distributor, MSD, Digital E-Curve, SB/BB Chevrolet

Chevrolet Small Block/Big Block Digital E-Curve Distributor by MSD®

Electronic advance selection and a built-in rev limiter replace conventional timing weights and springs.

The MSD® Digital E-Curve distributor controls timing electronically instead of using a conventional mechanical advance mechanism. Switch settings select 20 timing curves and five vacuum-advance curves, providing nearly 100 combinations without changing weights or springs. A built-in rev limiter can be set from 5,000 to 10,000 rpm. The magnetic trigger, field-replaceable internal ignition module and CNC-machined aluminum housing form a ready-to-run assembly that uses a compatible external coil rather than a separate ignition box. A sealed three-pin connector, Rynite cap and matching rotor complete the ignition connections.
