The pertonics sensor is mis-phased in relation to the rotor.
There is supposed to be a lucas specific pertronix unit, which should
put the trigger point at about the same position as where the points
would open.
You sure you have the right pertronics unit?
Is it mounted at the correct point on the advance plate?
Also it may be worth mentioning that although your timing shows
correct with a light, the rotor will be so misphased that the spark will
have to jump
a huge gap from the rotor to the cap, that you spark will be very weak, and
may even jump to an adjacent terminal in the cap.
This is to say that even if you didnt mind the the didtributor touching your
block, you shouldnt leave it this way.

The 13 you read is the number of cam degrees that the advance weights are
set for.
This is 26 degrees at the crank.
with a static of 8, and the 26 crank degrees, you should see a net advance
of 34
at 3500 RPM (with the vacuum line removed).
Good luck,
