Camshaft Manufacturers Description:
The Summit Stage 1 Ghost cam has slightly negative valve overlap and works great as a sleeper/stealth cam. Although a stock converter can be used, a 2,500-2,800 rpm stall converter is recommended. It also works great as a turbo cam. It has state-of-the-art lobe designs stable to well over 7,000 rpm with as little as 150 lbs. of seat pressure.
