Super six timing

12 BTDC + 18 Mech + 22 Vac = Super Six Setup. Runs great, Slight ping at the top end of WOT...could fix that by bumping the INT down a hair....but you usually ain't WOT daily..So...ehhh

So thats 12 Initial, a 9R Slot, and a 11R Vacuum Can
1 Heavy Spring and 1 Med/Light Spring. Comes in good thru the RPMs.
Vacuum Can adjusted Counter-clock wise to have it come in with light pedal/high vacuum. *Usually all the way counter, starts around 12ish and pulls on in till about 16ish*

If you have a slot bigger than 9R, FBO Systems
Set on the 16* mark....
9R Slot =.387
16* Mark =.393....close enough...

My Super Six in the Twister idles steady around 950 in Neutral, 650 in gear, and 550 in gear with AC on
