Default spark dwell time tuning ?

Ive heard GM sets them at 4-5ms and they can be safely bumped to 6-7ms
Has anyone tuned this I would think it would be worth it.
How do you log the dwell time with hpt?
Anyone have any good links I can read on?

Sounds like it affects how long the coil packs build up a charge, which results in a bigger/hotter/stronger spark... build it up too long and the coil packs go "poof"

According to some of the guys there sounds like NA it's not very crucial... more for FI guys where there's so much fuel in the cylinder to ignite , a stronger spark is needed?
