I wholeheartedly agree Dave, the price is good for what you get.
I have been considering buying a LS3 to replace my LS1 at $7950.00

The thing I'm unclear about it how the computer and wiring is sorted as I'm quite new to modern cars.

I have also considered a Harrop Supercharger but that alone is $9000 + cam, lifters, extractors and mafless tune.
