NewZed Posted December 20, 2010 Share Posted December 20, 2010 (edited) Looking for memories from your past... Unlike many here, I am still working with the 30+ year old mechanical distributor. I have a couple of distributors that have numbers on the advance mechanisms that don't match the specs. from the FSM. Am I correct in reading the numbers on these two distributors as 11 and 9.5 degrees of centrifugal advance at the distributor shaft? Which should translate to 22 and 19 degrees at the crankshaft? If so, they must be modified from stock, or there were more varieties from the factory than listed. They are a D6F4-01 (should be 10 [20] degrees, from FSM) from a 1976 280Z and a D6F5-02 from a 1978 (should be 9 [18] from FSM). Both manual transmission. Pictures are attached. Thanks for any insights. Edit - What I'm really wondering is how a 9.5 and an 11 got in to two different 280Z distributors. But any comments about the changes in distributors from year to year would be appreciated. Edited December 20, 2010 by NewZed Quote Link to comment Share on other sites More sharing options...
