When an engine has more than 50,000 miles on it, it’s a good idea to inspect the entire valvetrain.

You can expect a major improvement in throttle response and torque... Chevy Small-Block Chevy Big-Block Chrysler Small-Block Chrysler Big-Block Ford Small-Block Ford Big-Block Oldsmobile Pontiac Designed for street high-performance applications, Performer RPM cams provide power from 1500 to 6500 rpm.

These hydraulic lifter camshafts are dyno-matched to Performer RPM manifolds for high-rpm horsepower while still maintaining acceptable low-end torque.

Designed for optimum torque from the low-end to the mid-range, Performer-Plus camshafts match with Performer manifolds for vehicles operating from off-idle to 5500 rpm.

They are smooth idling cams for daily drivers, trucks, vans, RVs and 4x4s.

For higher boost applications, consider a three-angle, “street-type” valve grind to promote better cooling.

With the additional combustion temperatures normally generated in a supercharged engine, the wider valve seats will provide better cooling of the valves, and the three-angle valve grind will provide better sealing of the valves.With 10 to 12 inches of manifold vacuum at idle, Performer RPM cams have more lift and duration than most street camshafts...AMCChevy Small-Block Chevy Big-Block Chrysler Small-Block Chrysler Big-Block Ford Small-Block Ford Big-Block Oldsmobile Pontiac Designed to work with Torker II manifolds for performance from 2500 to 6500 rpm, these camshafts are ideal for high-performance street, drag or marine applications.Forged, low compression pistons (7-8:1) are the best choice for performance applications.Higher compression ratios are not recommended because of overheating and excessive final compression ratios (see the final Compression Ratio chart in this catalog).Cast cranks are only recommended when the boost levels are below 10lbs. When rebuilding, cranks should not be less then a 10/10 grind and should have all the trick work as you would for any high performance factory rods will work well for mild blower systems up to 8-10lbs. Factory and after market steel rods with heavy duty rod bolts are recommended and required for high performance applications.
