I was just talking to the place that's (hopefully) help me install all the parts in the motor ... anyway, they suggested I should sometime look into replacing the stock coils with something better, like e.g. MSD ... I just did a quick google on it, as I mainly knew MSD for carburator engines ...
The numbers and diagrams for the LS1 coil replacement look impressive, with something like three times the output from the stock ones ... but is there a point in putting $600 upwards into different coils? (I'm talking moderately modded street-car, not 9s racecar)
