Any books on vacuum advance and timing???????

You don't need a book.

Step 1:

Block vacuum advance off; Set initial timing 32-38 initial. Take trip to verify best performance. Fast burn heads take less timing!

Step 2:

Connect vacuum set 12-16 degrees for best economy. Add till it bucks, then back it off a couple degrees. This DOES NOT AFFECT PERFORMANCE! It falls off once you get above the RPM vacuum it takes to make it work.

Step 3:

Verify 46-52 total. Fast burn heads take less timing! Dun.
