- This distributor has both a "mechanical advance" (with return springs and advance weights that swing out dependent upon engine rpm) and a "vacuum advance" canister on the side of the distributor body. The vacuum advance uses a small vacuum hose that attaches to the carburetor which allows the ignition to be advanced during periods of high intake manifold vacuum (part-throttle and deceleration mostly) which contribute greatly to engine efficiency, economy, cooling, and throttle response.
- A small allen wrench inserted into the vacuum hose connection of the vacuum canister allows the tuner to adjust the amount of vacuum-induced advance. Different advance weights and return springs from an “Advance Weight Kit” intended for a GM points-type distributor (such as our 550-927) can be used to vary the rate and amount of advance induced by the increase of engine rpm.
- With more radical or “lopey” cams, the mechanical advance becomes more important. The vacuum signal becomes erratic in those situations and the vacuum advance canister becomes ineffective.
- Diameter at base of cap on outside of hold down boss is 5”. Cap is 4-1/32” tall.
NotesCap O.D. is 4-1/8". The distance from mounting shoulder to top of distributor cap is 7-3/4" and 6-5/8" to top of rotor button (minus cap).
