iginiton timing questions

Your vehicle is not a "lean burn" thing, I hope?


Anything built from 66 onwards in the state of CA, and Federally (U.S.) from 68 onwards is some sort of "smog" application. Some of 'em just got worse and worse as the years went on.

Indeed some stock dist's can result in an over-advanced condition if all you do is bump up the initial timing.

Generally speaking, most stock (especially) smog dist's need the mechanical advance shortened for degrees of advance, and lighter springs installed for QUICKER mechanical advance.

Most stock dist's will accept an early vacuum can, so usually you can just get one that is for 66/67 and cure that EXCEPT that some "parts store" advance cans are nowhere near equivalent to stock figures. That is, they'll sell you one that fits "65-78" or some damn thing, and you hope it works OK.

If you download some of the factory manuals here:

The have the specs for advance in the rear part of the electrical section to give you some idea.
