    5.3 or 6.0

    I have got to change out my 5.3 it made it 245000 miles without a burp. It has started to leak coolant into the combustion chamber from somewhere. I can get the 6.0l crate motor for the escalade, or the new hi-po 5.3l crate motor. What should I do? The 4l60e just got built up to strong specs. I have 4:10 gears...
    Thanks
