Its probably the 6.2 liter V8 that is being intro'd in the new trucks. I've been reading about it being put into a lot of new cars as GM considers bringing out more and more RWD cars. There's supposedly gonna be a new Impala going back to RWD. The LS2 should never put out less than 400hp...besides those power levels (362hp/391lb-ft) match up pretty good with what the 6.2 puts out
