All of the following street and racing camshafts may appear to be small. These are proprietary lobes designed by RLD Performance not by others. These camshafts were specifically designed for Late model engines to use with our cylinder head port designs. These camshafts were designed with short seat timing and high lift. The lobes were all designed with the most aggressive hydraulic roller lobes available today. All of these camshafts have a maximum timing area “under the curve” for maximum performance. This camshaft line will maximize your combination and are best utilized as cubic inch specific depending on if you want to emphasize horsepower or torque. Please pay particular attention to the lift. In the non VVT 5.7/6.1 engines the valve guides will need to be cut down. Do not order a camshaft past your maximum spring lift. RLD Performance has a proven line of their own racing spring and hardware kits that were designed to work with these profiles.
Emissions warning – The following camshafts are for off road use only and are not 50 state smog legal to use on emission controlled vehicles.
- Designed to maximize port flow by cubic inch application.
2. Designed to maximize valve spring limitations for maximum performance.
3. Most aggressive ramp designs available with maximum lobe area.
4. Camshaft Characteristics include increased throttle response, a broad torque curve, minimal dip in the low speed torque curve and peak horsepower with minimal drop off at peak RPM. - Factory lift is limited to .550 due to the distance between the retainer and valve stem seal. You must cut down the cylinder head valve guides and install a new oil seal for retainer to valve stem clearance on all camshaft profiles.
- All camshafts require a .650 lift spring.
RLD-H1 low lift
Duration @.006 264/272, w 1.6 .555/.556, LSA 114 1,500-7,000 rpm
Comments- Due to the popularity of the H1 design, this low lift camshaft was designed as a universal upgrade camshaft for the 5.7 and larger V-8’s without changing factory valve train components.
RLD-H1
Duration @ .006 265/275, w 1.6 .592/.600, LSA 114 1,500-7,500 rpm
Comments – Baseline stage one performance camshaft for the 5.7-6.5L Hemi on the street. Emphasizes a balanced engine with the RLD cylinder heads and ported intake. Huge midrange torque. Outstanding turbo/supercharger cam. No overlap at .050 lift. Stall converter is optional. See listed dyno sheet 536 HP/ 498 T at flywheel tested on an SAE Engine Dyno and 445 HP / 448 T on a chassis dyno.
