The Xtreme Energy XR280HR retrofit hydraulic roller (230/236) provides a street-focused upgrade requiring about 9.5:1 compression and a 3.91+ gear. It calls for a 2500+ stall converter and benefits from an aftermarket intake and headers. The cam raises midrange responsiveness while using hydraulic-roller valvetrain convenience for daily use when supported by proper drivetrain components.
