I ended up clocking over 760 MILES... not as good on the fuel economy though, I figured I got about 12/100, since I took a detour through the snowy mountains run onto Cooma, then through to Sydney. Lost a fair fit of fuel economy getting stuck behind horse floats in the mountains and getting stuck in traffic 3 times on the Highway, thanks to 3 separate accidents, two of which happened only minutes before we got there.
Enjoyed every minute... despite the slow crawl home.
the LS1 with a tune is a great motor and Chris and Toby know their stuff... ;-)
