I'm thinking of installing a camshaft in my M6. I will be running 4.10's, but thats not important right now. I'm wondering how much your miles per gallon went down after the cam install. If you could put your cam, miles per gallon after cam install, auto or manual and rear end gears, that would help me a bunch
