Crank degrees crank RPM
16* 1800
22* 2300
VAC Advance FROM MANIFOLD 14*@ 15”
Initial doesn't matter much, it's the 1800 and 2300 rpms totals that count. Seems 1800/16* maximizes torque on a stock flatty. One of the wiser grey hair here posted it and I had to try it. It works.
I have always used the "hot timing" method with a timing tape or adjustable timing light as long as you have an accurate TDC.
Manifold vacuum is a tremendous advantage with low end drivability and low speed (cruzing) cooling
