Summit Racing™ Pro Hemi Automotive Camshafts

Summit Racing™ Pro Hemi automotive camshafts are easy on the valvetrain and stable at high rpms. They work well with superchargers and nitrous, and will require springs, a tune, phaser limiter, and an MDS (multi-displacement system) delete. The smaller cams in this group have a noticeable lope and good power across the range, while the larger cams have a serious lope with strong top-end. Choose the one that best fits your purpose.

Notes:

* Pro Hemi automotive Stage 1 has a noticeable lope and works great in 5.7L as a daily driver. It makes good power through the range, and a tune and phaser limiter are required. A free flowing aftermarket exhaust is recommended.

* Pro Hemi automotive Stage 2 has a mild lope and works great in a daily driver. It makes good power through the range, and a tune and phaser limiter are required. A free flowing aftermarket exhaust is recommended.

* Pro Hemi automotive Stage 3 has a steady lope and is about the biggest cam to used in a daily driver. It makes great midrange and has good top end. It works with a factory converter, but a tune and phaser limiter are required, and free flowing aftermarket exhaust is recommended.

* Pro Hemi automotive Stage 4 has a strong lope and works good in weekend hot rods. It makes great midrange and has very good top end. It is the biggest cam we recommend with a factory converter, and a tune and phaser limiter is required. A free flowing aftermarket exhaust is also recommended.

* Pro Hemi automotive Stage 5 (or Stage 4 supercharged) camshafts provide a serious lope, great power in the mid-range, and a strong top-end. These cams require a tune, phaser limiter, an MDS (multi-displacement system) delete, and valve springs capable of .625 lift. We recommend a free flowing aftermarket exhaust and a 2800-3000 converter. Careful attention to piston-to-valve clearance is required. Fly cutting is generally not necessary.

* Pro Hemi automotive Stage 6 (or Stage 5 supercharged) camshafts achieve the top stages in each of these groups, providing a serious lope, great power in the mid-range, and a strong top-end. Each of these special cams require a tune, a phaser limiter, an MDS (multi-displacement system) delete, and valve springs capable of .625 lift. We recommend a free flowing aftermarket exhaust and a 3000-3200 converter. Careful attention to piston-to-valve clearance is required. Fly cutting is generally not necessary.
