Of course, with 590 dyno tested horsepower for the hydraulic roller cammed models, there’s an abundance of performance. The engine features a World Products MERLIN III cast iron block and MERLIN III aluminum heads, 4340 forged steel crank and H beam connecting rods, forged aluminum pistons and all the good stuff!
