Summit Racing™ Pro LS Automotive cams are affordable and designed in stages with very specific cam timing for each individual application in cathedral and rectangle port versions. This ensures maximum performance and gives you the idle you are looking for. The lobes are designed for stability at high rpm with the spring pressures found in quality .600 and .670 in. spring packs. Careful design guarantees the cams can be installed with minimal difficulty. Although piston to valve clearance should always be verified, the Stage 2 and 3 cams often allow for additional cylinder head milling. The Stage 4 cams often require no changes but can be degreed slightly different as needed. Starting with American bearing steel, they are precision machined on a Landis 3LB CNC grinder with CBN diamond wheels for unmatched quality.

Improved Racing oil cooler adapters have a low-profile for more header clearance. The adapters are machined from a single piece of billet aluminum and black anodized. For additional clearance with reliable sealing, they come with aluminum gaskets fitted with Viton® seals, and the adapter mounting holes are counter-bored so the mounting bolts fit flush with the adapter surface. Select Improved Racing oil cooler adapters are also available with a built-in thermostat. Oil coolers help prevent the oil from getting too hot, but are also prone to lowering oil temperatures too much, especially in colder weather or during highway driving. The rebuildable thermostat speeds warm-up and helps reduce engine wear and horsepower losses by preventing oil temperatures from dropping below optimal levels. Features and benefits * 100 percent bolt-on solution; no fabrication, bending, or line modification is required * Viton® seals throughout for maximum reliability * Oil exiting the adapter is filtered oil * 6061 T-6 billet aluminum construction with black MIL-A-8625 Type II anodized finish * Standard female -8 AN O-ring boss threads for optional anodized adapter fittings in your choice of -8 AN, -10 AN, or -12AN lines * Depending on application, includes port(s) for oil sensors or turbo oil supply * Includes all necessary hardware * Limited lifetime warranty
