The Z28 should get better mileage.

If you were to drive them about the same way then the Z28 should be getting better gas mileage.

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!

My 00 WS6 A4 gets around 20 MPG and my 96 Tahoe is about 15 MPG. I have not driven my Tahoe in three months.
