they aren't the same, the trucks had different ones, but they still will work fine. However, I believe that all of the cars had the same ones, but I could be wrong.

The ls2 also has different coils and I tried searching awhile ago to see if they would fit but no luck hope someone can chime in with more info.

I know the trucks use longer coils as the coil packs are larger. The LS2 coil packs are a different shape. I think they all pretty much supply the same amount of spark. I've heard of people saying the truck coils are a little better, but I'm not quite sure why.

I think the truck coils are like heavier duty (more heat resistant) or something.

How to Build High-Performance Chevy LS1/LS6 V-8s states that there are three versions of coils used on the Gen III V-8 that are distinguishable by their external shape or their usage. There are two truck coils many hot-rodders describe by their external appearance- they are called the "round" & "triangle" coils. The LS1- engine coils are more rectangular in shape with the spark plug wire connector at the bottom of the coil. The triangle truck coil looks similar to the LS1 coils but the plug wire connector is in the midsection of the coil. We're told by GM engineers that the differences are merely external, as a result of the three different coil suppliers. Many engine builders believe the round truck coils perform better in high-horsepower applications than the other two coils. That all comes right out of the book. Hope this cleans things up a little. I'm not sure from looking at the pic's in the book about the coil brackets, they may have to be changed to match coils you use.
