Buying advice

Consider your engine's specific needs: for high-RPM racing, opt for billet distributors with adjustable timing; for street use, a good value option with vacuum advance may suffice. Verify compatibility with your engine make, model, and ignition system (points vs. electronic). Check that the distributor gear matches your camshaft material. Look for units with replaceable cap and rotor for longevity.
