A gt2560r will not get to at least 300hp. It taps out around 280hp.
Under the most ideal setup, it will maybe hit 300hp, maybe.
You need a gt2871r or a efr6258 for 300+hp.
8.6:1 Supertechs in 84mm with Weisco rings, like Lars said above. Most popular.
you also must have forged connecting rods.
300hp ain't cheap. Around $6-8k once you figure supporting drivetrain upgrades.
