Why so popular? Well according to a local C5 Z06 owner who knows everything about the LSx motor, you can pull a 5.3 LS truck motor for $500, twin turbo it and make over 1000HP without touching anything. I mean who can say "no" to that bro?
He also went on to say the reason GM upgraded the LS7 with extended cylinder bore, dry sump oil system and titanium head components was simply because they needed new features to sell the car.
Sadly he isn't joking.......
