Modded or no mods doesn't matter - engine issue still exsists. If you check out the threads over on the corvette forums 50% of their threads are either about Blown Engines, Engine Rebuilds, or Valve/head repair maintenance. Also the Z06's have oil starvation issues with the factory setup that will cause the engine to blow as well on high G turns.

The E9X you can take it out and run 30+ track days and not worry about it. That is the reliability I was talking about.
