I've seen guys with stock bottom end 5.0s making tons of power too, but that doesn't mean it's going to last in a high rpm for 20 minutes at a time environment, in fact two friends of mine have blown new LS motors in their cars at the track, one with stock power, the other with about 450 to the wheels. I've read the LS1 weighs 430 lbs w/gear, I've never weighed them so I can easily be wrong since I'm quoting internet bozos. If taking 50 lbs off of the 302 w/heads makes them 450lbs, you'd be at either a 20lb or 55lb difference. I guess depending on who's right, there's a medium or small difference.
As I said, everything is available but it all adds up, wiring, driveshaft, motor mounts (I didn't know you could just use 4.6L mounts- does that put the trans in the right place for the shifter, I wonder), accessories, flywheel, balancer, etc.
Yes, the LS1 can make 400hp with a cam and other bolt ons, you can make 400 hp out of a 302 with heads, cam and other bolt ons so price difference is still close.
I won't argue the LS series motor is hard to beat, I'm just argueing the value propostion in stuffing it in a Mustang unless you have one laying around.
