This is installed in my 1972 Jensen SP. Installation details (and photos) are on this site in another thread.
Note that this advance curve might be a little bit too aggressive in the heat of summer.
The car starts and runs easily. It seems to be a little bit smoother than with the old distributor but that just might be my rose-tinted glasses working.
Fuel consumption is better than before at highway speeds. On a pure highway run I get a little over 20 mpg from this beast, primarily (in my opinion) due to being able to run 50° BTDC at 1700 rpm with a light load. No performance testing has been done.
