Owned a 2008 Corvette Z06 with a 427 and a 6 speed manual for 6 years in Jetstream Blue. Sold it last year never trusted the LS7 motor. Week link with the valve guides motors even with very low miles blowing. It's so bad there a class action suit against Chevy over the issue. I was lucky with mine but I didn't want to push the issue. After 6 years I was over it.
You can bullet proof this issue for a couple grand.
