Think of this also...which one do you want to drive faster/harder in? The Z28 will get better gas millage, but my driving habits would probably make up for the difference.

I haven't checked since I put the cam in my car but stock I was getting around 18-20 mpg. My 2000 GMC 1500 ex. cab Z71 (5.3 LS) has never gotten better than 15 mpg. I'm guessing there about the same now if the car still isn't a little better!
