Make sure your vac advance is unhooked while you time it. Also grab a vacuum gauge and tune your carb while you are at it. Good luck. [IMG]http://i66.tinypic.com/pui5j.jpg[/IMG] Coming soon!!!!

With CAP TDC if a stick and 5BTDC if auto. 68's may be (& very probably are) different. I'm assuming a stock 440 & 10 BTDC is a good ballpark initial & if doesn't ping your fine. live every 24 hour block of time like it's your last day on earth

Then no risk of too much timing etc. Depending on the rest of the combo, you might want to make some changes to dist springs, slots etc..

Depends, some distributors have so much initial timing built into them if you do this you end up with 0* initial and some combos won't even want to fire up with that little spark.
