The truck ignition coil upgrade:
Doing the swap:
The coils are 10457730 (GM part number) (AC Delco part number D585), eight coils needed.
The coil mounting brackets are 10457736 (GM part number), two brackets needed.
The coil harnesses are 12601824 (GM part number) two harnesses needed.
Good luck! Paul Bell

Hey Christian, looks like a nice install.
It's probably best to show pictures in a new post so people know they're new.
You mentioned to me the car wouldn't crank-is it all fixed now and running on the new coils? What was the problem?
Get some better wires. I recommend Granatelli zero Ohm wires.

Let me know what section it will benefit the best and I will create a thread.
As I got all components separately, I assembled everything...and inverted the harness.
Cylinder 1 was at 7 and cylinder 2 was at 8...just flipped 180* and cranked immediately!!!
I went for a drive logging as usual...the AFR got leaner everywhere!!!
I decided to launch a WOT on my usual private road with my VBOX...and undeniably power is higher...
A dyno session back to back with LS6 OEM NEW COILS (changing the all hardware is 10 minutes) is programmed and I will report.

Hey that's great. I was only saying to post it in a new reply, not an existing reply.
Let us know how that dyno session goes.
Most folks (including me) notice better engine response when going to these coils. Power increase is debatable-but in my opinion it adds something.

Agreed. Using just one bolt will cause the coils to vibrate. This has been discussed elswhere.
And coils under the car? Really? How's that working out in the rain?

Blasphemy!!!!
They are very secure and tightened down good. The coils aren't loose. Never thought of putting them under car but sometimes I drive when the roads are wet so that would be out for me. Cool idea though. I will relocate else where is the future off the valve covers
