Sportsman 438" 875-920hp

This engine package is one of my personal favorites. We set out to design a naturally-aspirated 9.5" deck engine that can make 900hp without getting into anything exotic; it is still an internal wet sump engine, standard cam core, standard .874" lifter, stainless valves, and an inline head. We spent countless hours on the design and testing of this package and ended up with a combination that is easy enough on valvetrain parts to live in a bracket car, simple to maintain, and still makes great power. 

Power Numbers: 876hp @7700rpm (at 14:1 and we can do 15:1 for the same price)
