I don't know much about LSx motors other than their are zillions of them out there already and they seem remarkably cheap and durable. Might not be that much more expensive to build 1K turbo V8 hp than 600 turbo V8 hp. The guy may have wanted to do it once with the best parts and dial it back electronically if it's too much. I wouldn't really want to do a car exactly like that (although a really well suspended twin turbo SBF early Mustang would rock my world) but the owner must have wanted it that way.
