Tim-All TR6 dist curves are not created equal. I was looking at a Bentley
manual at the various dist. specs. and noticed that the dist. used on 71 cars
(41352) is quite different. The static timing is 4 deg BTDC and does not reach
max advance of 26-30 deg until 5600 rpm. Most of the other dist. start with
about 12 deg static, advance quicker, and have less total advance. The PI cars
start with 11 deg, and reach max advance of 12-16 deg at only 2600 rpm. I guess
the bottom line is that using 10 deg. static timing on the 71 dist. will give
too much total advance, if the compression has been increased.
