Total mechanical advance question
Regarding total mechanical advance; (initial plus centrifical), on a stock 1965 326 engine utilizing manifold vacuum.
I have read that 34°-36° is preferred for total mechanical advance. My HEI distributor has 20° total centrifugal advance. I usually like to set my initial timing in the 8°-10° range, but if I set it at 10°, it will only have a total of 30° total mechanical advance. And worse yet, if I set initial at 6° which is the stock listing setting, I would only have 26° total mechanical advance. So right now I have initial timing at 14° giving me 34° total mechanical. It starts OK, but can anyone shed some light on this for me? Thank you. |
