Is the pulley size the only differences? I've searched but can't find a clear answer. I found a used LS1 kit, but I have a LS2 for my Chevelle. Thanks.

 

I was wondering the same thing. I have an LS2 but I'm running it with a cable throttle body and, after looking at some Maggie kits installed, I'm not sure the throttle cable cam will clear the jack shaft.

 

I read on the post where I'm looking at buying it it costs about 300 bucks to make a few small changes for it to work on an LS2. I'm just trying to confirm, before I buy it and realize it isn't what I need.

 

I know some of the pro's here have done this swap...
