Well it very near stock anyway. That is the only mod to the engine to my knowledge but you might want to check with Panel first.



The ecotec engine will fail at around 400 hp. 383 hp if I remember correctly from the testing done on that engine for drag racing research. At 750 hp you need aftermarket crank/rods/pistons/head gaskets/head mods, intake and exhaust.
