The MSD Black Chrysler 426-440 Ready-to-Run distributor brings the same easy, three-wire installation as MSD's Ready-to-Run line to Chrysler 426 and 440 engines in a stealthy black anodized finish — no ignition box needed. A maintenance-free magnetic pickup accurately triggers the built-in module, and the increased output easily outperforms stock ignitions, smoothing idle, improving starts, and extending the usable rpm range. MSD's adjustable mechanical advance lets the timing curve be custom-tailored, and a vacuum advance canister helps economy. A separate tach circuit makes it easy to trigger a tach or an aftermarket EFI system such as Atomic EFI.
