Worlds Most Powerful Big Block!
The Sirio .27 has been very compeditive on the market with the claimed horsepower but now its being bumped down to second. RB Concepts has just made the .28 TM! It doesn't have any power specs but RB Concepts makes the best engines in the world and I'm shure a .28 will have massive amounts of power.
