Highlights

• Bolt in cams for 88 CID engines with stock compression ratios
• Increases valve timing accuracy by eliminating timing chain lash and loosely fit stock chain drive
• Reverses the rear cam's direction of rotation, providing additional operating clearance between cam lobes; resulting in higher cam lifts that are possible with the gear kit
• Material must be removed from inner surface of the stock gear cover to install
• S&S recommends that adjustable pushrod/cover kit to be used
