Do I need to be nerves having the timing adv so much? I know the old saying is "running lean is running mean". Also I have a noob question. How do I know when it starts knocking? Is it loud? Will I hear it with my head under the wood or would I need to drive the truck?
Thanks again for all the help.

Just listen for a rattle sound like rocks in a metal can. You will hear it from the drivers seat. Best way to test for pinging is when you get into high gear at a slow speed, step on the loud pedal without shifting down a gear. If it rattles, pull it back a couple degrees.
Every motor combo is different. I ran an aluminum headed 350 with 22 initial, 12 in the dizzy and 10 from the vac pot.
