Loads of LS engines around because they outlast the rig they were in. Junk doesn't rust here and we have a bunch of these engines around. I blame it on the 4l60e. After three of those fail you just scrap the truck.Did you forget where you live? I stopped at TSC for dag food, and saw a "newer" Silverado with the wheel arches GONE in the bed. No wonder there are so many LS out there; the trucks surrounding them rotted away!
