ls1 coil packs on an ls2 Is there a way to use ls1 coil packs on an ls2? the ls2 is center bolt valve covers and the ls1 is perimiter so its not as simple as switching them. does anyone make a conversion bracket because the ls2 coil packs are in the way of my ls1 fuel rail.

Be careful . . . I called MSD about the coil packs for the LS2 and they said the coils are not available yet. They have a different part number. I was also told the electrical connection is different.

Weird.
I run LS1 coil packs on my LS2. The coils and valve covers came from an 01 LS1 and were no trouble at all to fit to an 05 LS2.
The 2 main (coil group) electrical connectors are not different, but the 8 tiny connectors to each individual coil are different. The LS2 plug leads are L shaped and fit better.
LS2.
LS1.
Note: LS2 coils are much "taller" and will hit on some LS1 fuel rails.

Well the LS1 coil packs bolt directly to the valve cover. and the ls2 bolts to a bracket.
heres a pic of the ls1 Valve covers/and coil packs.

Valve covers on '99 and up LS1's were all center bolt right? So yours must be a '98? Like he said before, I think the coils are the same, just mounted differently. So just get the different mounting brackets and that should fix the problem.
