Anyone had to relocate their 3800sc coil because its hitting the hood hinge? Also did you swap valve covers so the oil fill is at the rear instead of up on the firewall?

From what I have read in my research doing the swap, the coils are usually relocated to near the battery, and the battery is relocated under the spare tire in the front... Also, yes, the valve covers are usually swapped so that the oil fill is easy to access.

The icm does need to be well grounded but not necessarily to the engine per se. I usually mount mine on the trunk wall above the O2 sensor and just ground it back to the engine with and extra ground strap.

Put my coil on the trunk side opposite the fire wall. Put my computer up under the drivers side louver with an aluminum cover cause people said it puts out a lot of heat in the passenger compartment.

You need to move the coil packs, or cut up / loose the right hinge for the most part. I am moving my coil packs to where the alternator used to be, pretty much the same spot, just on the other side of the engine.

You will need to cut the bracket that the coil packet mounts to, as you still need the idler pulley, and the tensioner.


You can check out the post in my thread where I did just that.

If a lot of you guys are relocating your cool packs to where the battery was what are you doing for spark plug wires ? Other than making custom wires, is there a particular car / truck set that works out for the length ? Any ideas of where to route them ? Not trying to hijack but thought this would apply to this thread.

I mounted mine vertical on the right strut tower, worked well with battery in place. Now I have them mounted where the battery was, and have the battery up front. And yes, you swap the valve covers.

I had the plug wires from the donor that were in pretty good condition. I picked up 2 48" wires from Autozone that worked out pretty well, mixed with the others. I routed them low, out of sight. Depending on how you route your wires, I have heard that stock will work OK- you might need an extra #6 wire from the pick and pull. If you want an absolute perfect fit, then making your own with a universal kit is probably the way to go.
