I would love a 6.2 but the price ouch. I took my build of aftermarket parts and added to the price of the new 392 and the numbers were around 100k, it made more sense to just buy a v8 as well. I say your better off dropping a V8 in because both your JL and JT are awesome builds. I did like the video Bubba did on the LS vs. Hemi but at the same time I have been watching some videos on Motech and they are awesome as well. The thing that has me leaning towards the 6.2 from my understanding is easier plug and play, you can keep cruse control, and cooling is better. If I misunderstood that please correct me.
