Camshaft Manufacturers Description: The Summit Stage 2 Turbo cam is specifically developed for turbocharged applications. It will spool quickly and minimizes reversion caused by high turbine inlet pressures. It also works well as a high-lift version of the SUM-8714 Stage 4 truck cam. It has state-of-the-art lobe designs stable to well over 7000 rpm with as little as 150 lbs. of seat pressure.

Quantity: Sold individually.

Notes: Not for AFM or VVT equipped engines. Summit Pro LS cams are designed for engines swapped into pre-pollution controlled vehicles. They are not for use in registered emissions-controlled vehicles operated on public highways and roads. 3-bolt camshaft, computer tuning required.

In-Store Pickup: Choose In-store pick-up (OH, NV, GA, TX) on our web site.

The Summit Racing Pro LS Turbo cams are affordable and specifically designed to optimize cam timing with turbochargers. The lobes are stable up to 7,000-plus rpm with the exhaust lobes opening softly against high cylinder pressure for reduced stress on the valve train. Overlap has also been reduced in order to prevent reversion, which is typically seen with higher turbine inlet pressures. They come in distinct stages that give you the idle, spool, and power characteristics that match your engine and turbocharger. Starting with American bearing steel, they are precision machined on a Landis 3LB CNC grinder with CBN diamond wheels for unmatched quality. The lobes have been designed for stability at high rpm with the spring pressures found in commonly available quality spring packs.

Answer This Question


will stock pushrods work with this cam ?

Asked by GREGORY on May 09, 2019


Thank you for your question. The Summit 8706 Pro LS turbo camshaft will likely need longer pushrods due to the designed of the higher lift camshaft and is dependant on engine deck height, if the cylinder head was surfaced, gasket thickness and other factors that affect such things.
