Quick question about coil packs

Are the coil packs on non supercharged motors (3800 series II) the same as the coil packs on supercharged motors? Will the coils interchange---
3.1, 3.4, 3.8, etc...?? Thanks!

yes, GM used the same coil packs on all the engines you mentioned including the Supercharged 3800. The only exception is the older 3800 with the Magnavox system, where there was only a single coil assembly.
