Quote:If you are running a high performance, high compression [or blown] engine, then a high energy ignition will be a decided advantage, however, if you're like me, running a basicly stock engine, then the Pertronix unit is a good thing. I simply wanted a 'points replacement' system & I was offered a low mileage, pre loved Pertronix system at an attractive price which has since been fitted & works well.

Engine idle smoothness has been improved & I have picked up another half inch of mercury of vacuum at 600 rpm, so that simply means that it is making even better use of the tiny bit of fuel that is metered in there.
Easier starting, smoother running & a perception of better mileage, sounds like a bonus to me.
