Modified by Aldon to their Yellow distributor spec,original 25D with vacuum advance for originality on non-Aplus performance road engines. Once the engine has been modified, it will invariably require a different ignition curve-especially when compression ratios have been raised and camshafts changed. There is no substitute for a tailor-made distributor determined by an engine or chassis dyno session, however this can be prohibitively expensive! We offer the Aldon Automotive range of distributors for A Series engines. For road use it is advisable to use the vacuum advance for economy. Many say, incorrectly, that this over-advances ignition, causing detonation in performance engines. That is not true as the vacuum advance only works at partial throttle openings, not under load with full throttle when no manifold vacuum exists!
