GM and Ford have to make this power reliably enough to warranty. The current LSA and LS3 are not stout enough to offer over 700hp under warranty. It's just too risky. It would however be very simple to equip either with the proper rotating assembly to do so.

I have not "bolted on" an aftermarket blower or Nitrous system. My Camaro has a LSA engine...with bolt ons.
The LSA is more durable than an LS3. Steel crank, better rods and pistons and a better block than the LS3. Sure the piston and rods are the same material but they are beefier.
Now I agree that the LSA probably would not validate for 700 horsepower. But until GM tests it at lets say..... 590 horsepower we won't know.
