If you really want to know which is more reliable and works better just go to your local race track,where you'll find probably 9 out of ten cars running msd systems,and for good reasons...
can`t argue that, like you said race track. if my car were a race track only car, no doubt would i use an msd set up. i just don`t trust them for a lot of road use. seen too many go bad on the road. thanks
