Very cool, I have my eye on an LS swap as well. I know the LC9 is an aluminum block and all but I think most will be a lot happier with the LC9/LS3 than an iron block truck motor. From my minimal research, the iron block/aluminum head LS set up weighs about the same as a traditional Pontiac motor with AL heads while the AL LS blocks weigh about 100 lbs less. Removing 100 lbs off of the front of one of these cars normally results in a ton of compromises most of which are undesirable.
For me I am less concerned about emissions and need to retain the original transmission location for my TKO/mechanical linkage set up. I know SDPC makes a LS pivot ball adapter but I am a bit concerned about the frame bracket/engine mounts and header configuration. Holley seems to make the most well sorted out set up but it does relocate the engine 3/8" toward the center and down. I figure there is enough slop that I should be able to accommodate the change but who knows?
