I've purchased everything I need and am working on setting up Queen (the 4T80e Turbo Park Avenue) with LS "truck" coils. The conversion is pretty straightforward after finding the key component to drive the coils.
Here's a list of everything I bought for the conversion:
Buick Ignition Interface from DynamicEFI.com:
The interface shown is not for the ICM used on the series 3800s, you need to specify when ordering that you want a "TYPE 2" interface as opposed to the type 1.
Coils, wires, heat boots, and coil connectors:
Everything laid out for the front bank:
These wiring instructions can also be found on DynamicEFI's website:
There is no cover available for the Type 2 interface, so I will also be designing and 3D printing a cover for it, hopefully one that can use the stock length coil mounting bolts.
Some more pics of the 3D printed coil mount:
The holes in the coils are 7mm and I'll need 25 mm length for my specific mounting plan. The mount has hex slots perfect size to compress a lock nut into the back. I always design my parts to avoid needing to handle a nut and bolt at the same time during install.
The coil mount bracket will be held on by clamping it to the oil filler neck attachment point on the valve cover (not to the neck itself). There are also kex slots in the bottom and holes for 5mm hardware.
