First: ignition, you may or may not have read I'm building a boosted 250 and purchased: a DSII Dizzy and a GM 5 pin module. The actual wiring is SIMPLE, blissfully so. But I'm sort of stumped on timing it.... granted it just came in the mail but still. From my understanding there are three things that contribute to timing...
the actual position of the distributor in relation to the camshaft and thus TDC, known as static timing?
The vaccuum, which from what I saw actually pulls on the pickup thus changing its position in relation to TDC, known as vacuum advance.
Some sort of rotating weight and spring system which moves the distributor plate, known as centrifugal advance.
Knowing that I plan on putting a check valve on the vaccuum advance and that my module can retard the timing by 5*.....
How can I recurve my distributor/set vacuum advance....? I understand MR Gasket sells a kit for the centrifugal advance...
What kind of timing should I be shooting for in each of the three things? I plan on tuning it while it's running N/A to minimize the chance that any mess-ups on my part will break something but information would still be handy! Just ball parks even.
