AR-7200: This grind is for street use when few or no other modifications are made to the engine. The most effective power range is 3200-7200, with a tremendous improvement in acceleration over the stock cams. It will rev to over 7600.

INTAKE: 38/70     EXHAUST: 74/34     DURATION: 288     LIFT: .350"

        Necessary mods: PAECO valve springs (a one point compression boost, free-flow exhaust system, or racing ignition will all add even more power but are not mandatory).

AR-8000: This grind has an unusually broad torque curve and can be used as a wild street grind in addition to slaloms and solo events, or regional racing. The best power range is 3500-8000. INTAKE: 44/76     EXHAUST: 80/40     DURATION: 300     LIFT. 380"

        Necessary mods: PAECO valve springs and retainers, 10-11:1 compression, and racing ignition. (A modified cylinder head and a free-flow exhaust system will allow more power, but are not mandatory.)

AR-8600: This grind is a screamer and delivers tremendous power, but is for racing only. The best power band is 4400-8600 rpm, and it will rev to well over 9500 in a properly prepared engine. INTAKE: 52/85     EXHAUST: 88/48     DURATION: 316     LIFT: .415"

SP-6000: Designed for a stock or only slightly modified engine, this cam gives a very healthy acceleration boost. Idle is fast but smooth. A one point increase in compression is effective, but not required. The best power range is 2200-6000 rpm, and it tops out at 7000.                     INTAKE: 27/59     EXHAUST: 63/23     DURATION: 266    LIFT: .379"

        Necessary mods: PAECO Hi-rpm springs, retainers, and lifters (an exhaust header, Prima-Power free-flow muffler system, racing ignition, and Weber carbs will add even more power, but are not mandatory).

SP-6600: This is a wild street grind, also good for slaloms and solo events. It gives tremendous acceleration and a nice boost in top speed. The idle is lopey. Best power is 3000-6600 rpm with a max of 7500. INTAKE: 29/61     EXHAUST: 65/25     DURATION: 270    LIFT: .412

        Necessary mods: Full PAECO valve train, 10-11:1 compression, exhaust header, Lumenition ignition (A modified cylinder head, Prima-Power system, and a Weber carburetor will provide even more power, but are not required)

SP-7200: This is a racing camshaft, not for street use. The best power range is 3800-7200 rpm, and it will rev to 8000, giving extremely strong acceleration plus a big boost in top speed. This one is great for SCCA events and also for Vintage racing.   INTAKE: 42/73     EXHAUST: 77/38 DURATION: 295    LIFT:.460"

        Necessary mods: Full PAECO valve train, 11-12:1 compression, exhaust header, racing ignition, modified cylinder head (A high ratio rear axle is optional).

SP-8000: This grind is for all-out racing at the National level. It gives extremely high revs, and when coupled with a high ratio rear axle, provides unbelievable acceleration. The best power range is 4200-8000 RPM, and it will rev to 8600.   INTAKE: 45/77     EXHAUST: 81/41 DURATION: 302     LIFT: .480:

        Necessary mods: Full PAECO valve train, 12-14:1 compression, full modified cylinder head, racing exhaust header, racing ignition, improved carburetion, high ratio rear axle.
