LS3 Coil Packs

Does anyone out there know how I could get a set of new LS3 coil packs? And the wire harnesses that go with it?

I swear this post is now put up twice...

Yes you can use ls3 packs and same harness. In ls1 tech they confirmed this

HA!! Well, what you might be thinking of is another thread I had started a few days ago about the valve covers I had bought that up until a few days ago I had assumed that the valve covers I bought would use regular LS1 blaster coils. But I did find out the other day that I would have to get LS3 coils. As a matter of fact, I have already ordered and recieved them. Thanks a bunch Jon for looking into it though. I really appreciate it.

Hello,

Did you put the Holley valve covers on your LS1? Also did you have to change the wire harness when installing the LS3 coils? And was the coils factory GM coils part #12573190? Any help would really be appreciated.

Hi Bob.
Yes sir, I did. I did go ahead and order the LS3 wire harnesses also just in case the old LS1 wire harnesses wouldn't work with the new LS3 coils. I bought both of them from rockauto.com I don't remember what the part no's. were and I'm at work now. But when I get home tonight, I'll see if I can find those parts no's. for you.
