More Gen 3 questions

Thanks for the helpful responses - Ill use the MSD 6 - I wasnt sure if the 5.7 application in the sticky thread for Map63vette would work with a 6.1.

I guess I was too bound up over using the factory stuff when I don't need to.....

Do I assume the only other ignition component I'll need is the harness P# MSD 88863?

I'm not sure that's right, is there a different part number for a 5.7 harness (old coil packs) vs 6.1 harness (new coil packs- for new coil packs on 5.7 as well?).

Someone else will have to answer this one...
