Personally using a LS1 is not my cup of tea. Would rather listen to a Holden V8's unique crackle. It's a shame they dropped the development of the Holden V8.
I find a 253 worked to the eye balls much more interesting. A worked 308 is a great thing too! A fuel injected 5 Litre is even better. A LS1, that's just rolling over to the dark side.
