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.

Note: LS2 coils are much "taller" and will hit on some LS1 fuel rails.

i dont know how since like i said the ls2 is center bolt and my ls1 is perimiter. unless you guys are unbolting the coil packs themselves from the valve covers and using those? will the brackets be the same?

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.

You can order 2 center bolt coil brackets. They are under $9 each. Part number 12563288. Your 98 coils are the same as later models & will bolt to the newer bracket. I used a 98 harness engine harness to match the harness on the bracket. If you are going to use a newer engine harness I would get a new bracket harness or reconfigure the pins. Hope this makes sense to you.

Yeah i think im going to reposition the bracket down an inch or so. so itll be enough to clear and the covers will still go on.

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.
