I'd be interested to see exactly which cars the LS1 engine is fitted
to in the USA - I can't remember which ones off the top of my head,
but as I said before, I think that the Corvette is *not* one of the
cars that comes with it. Who knows, perhaps GM fits the LS1 to
a Monte Carlo or something ;)

That said, haven't there been some issues w/ LS1s in regards to oil
pumps failing? Or something along those lines..
