Race Series® Camchest kit with full-lift tappets

Quieter and smoother engine operation
Increases oil pressure, reservoir volume and engine oil flow
Engine temperatures 15°-35° lower
Oil temperatures 15°-30° lower
15-30 PSI additional oil pressure
Eliminates wet sumping, blow-by and oily air filters.
Single-piece thick-wall .165" pushrod reduces valvetrain vibrations and increases valve lift
Responds very well with slip-on exhausts and/or full system and high-flow air filter
Responds well with increased engine capacity and/or compression
Tappets with 0.200 total travel, designed with lower lobe lift speed to withstand high valve spring pressures, increase RPM before valve float, and provide more clearance for steep ramp cams and the exhaust cam lobe.
