438" SBF N/A 875hp+

This engine package is one of my personal favorites. We set out to design a naturally-aspirated 9.5" deck engine that can make just under 900hp without getting into anything (that most customers feel would be) exotic; it is still a wet sump engine, standard cam core, standard .874" lifter, stainless valves, and an inline head. More power could be obtained with a dry sump, canted valve deal, but this is more of the "Sportsman" option and with the 14:1 static compression it does not require the same caliber of race fuel as a higher compression engine. 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.
