Chevrolet Small Block/Big Block Dual Power Distributor by Davis Unified Ignition®

A compact billet housing and electronic module provide ignition control where a large HEI will not clear.

The Davis Unified Ignition® Dual Power distributor uses a compact billet housing for installations with limited blower, tunnel-ram or firewall clearance. Its Dyna-Module provides electronic ignition control and increased dwell; this is not a points-triggered distributor. The advance is calibrated for the engine combination, and a black HEI-terminal cap and rotor are included. A compatible external coil is required. Choose the distributor-only option or the package with the Inferno 2 coil. The manufacturer rates the paired Dual Power/Inferno 2 system to 10,000 rpm and permits plug gaps up to 0.055 inch when suitable for the engine.
