P4120701 Small Block Mech Tach drive
See if this helps. This a the advance curve of a SB tach drive distributor I ran on a machine. The blue line is from the mopar book pictured earlier in the thread.
Timing is in distributor degrees and rpm.
Marked up on the graph is a circle and timing in crank degrees and rpm. The circle represents the timing on an engine when the distributor is set to 35* at 2000 rpm.
