Have fitted 373 coil drivers but having trouble starting engine, not shaw if dwell settings are wright as i did have the same problem before i changed them but it has fixed the missing problem

dwell is set for the coil pack not the drivers. you wont kill 373's easily by over dwelling have a look on extraefi or diy autotune they have some info
