SBC, 6a box blaster coil billet distributor. Car ran at 185ish. Cruising along it would quit. Put new box in, new coil... nada... ended up being the 20$ magnetic pickup in the distributor. Part that sucked was yo had to pull the distributor, pull the gear and shaft to get to the 2 screws that held it in. Major headache but ran fin, no hiccups after.
