When my car gets put back together I am looking at running some "impressive" times, it will get pretty good gas mileage (especially for what it is and the times it should run). It will look good and act and perform fully street able.
Hence why i feel the LS1>LT1 far more in the world of tuning the car, mpg, power, 1/4 mile times. Drive to and from the track with the tops off (or on with the AC blasting)
I am assuming you know what the 1LE stands for by your response.
