| Edelbrock Rollin' Thunder camshafts are designed to improve horsepower and torque, produce a great sounding performance idle and provide excellent vacuum at idle to support power accessories. Rollin' Thunder camshafts feature more aggressive lift profiles than possible with conventional flat-tappet hydraulic cams, without excessive valve overlap that can compromise low rpm drivability; reduced friction provided by roller tappets makes this combination of accelerated valve lift and reduced duration possible. Edelbrock Rollin' Thunder camshafts are performance matched to Edelbrock Total Power Package components for proven performance.
Features Include:
•Performance - Roller camshafts produce higher lift velocity and faster valve action produces increased horsepower and torque gains
•Drivability - Produces great sounding idle while providing excellent vacuum at idle to support power accessories
•Durability - The smaller surface contact area of a roller tappet and reduced friction combined with stronger camshaft material (hardened steel or iron) ensures longer camshaft life
•Environmental - Can use ILSAC GF-4 oil, which lowers your engines emissions and does not require zinc or phosphate oil additives
•Economy - Reduced contact friction between the lifter and camshaft increases an engines fuel economy for better mileage potential
