Features
- Designed for 88" to 103" CID engines with compression ratios between 9:1 and 10:1
- Strongest from 3200-3700 rpm
- 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
- Material must be removed from inner surface of stock gear cover to install
- A hydraulic press and other professional level tools required to install kit
- S&S recommends that adjustable pushrod/cover kit be used
- Cam bearings and gasket must be replaced when installing new cams
- Kit includes camshafts, gearcover gasket, bearings, oil passage block off kit, retaining ring, o-ring, inner and outer gears
