Just a couple of quick questions:

Can someone please post the stock compression ratios for the 2001 and up LS1 and LS6 engines.

Are there any problems or issues running 11:1 on todays pump gas? I'm thinking about installing a set of AFR's milled to 62CC and am wondering if there is a down side to cutting them for 11:1 CR

Thanks

Stock CR is 10.1 to 1. Run premium fuel and you'll be just fine with 11.1 CR, that's the compression I plan on with 93 octane when I get some heads. Good luck with the modding
