5.3 LSX motor, turbo, ski mask (so people don't know who just raped them).   
There is a guy over on YB that did a junkyard 5.3 turbo build with one of these and is going 8's.  Granted, that car is backhalved I think, but you see the potential with these.     
I really looked at getting this car but to do the above build is out of my range of abilities.
