MSD Ignition and best Spark Plug Gap
Just installed the MSD 6 part no. 6420 Ignition Box. Hhave set my spark plug gaps at 1.40 mm and engine seems to be running ok. I have a 79 3.0. Is there anyone out there that has experimented with other gaps? porsche 101 suggests between 1.27 & 1.49 I believe. What tends to happen if you go smaller and if you go wider than 1.40? anyone....
