High Performance manufacturing tolerances are closer to control installed oil clearances, which reduce operating bearing pressure. The surface also exhibits a higher hardness. The LS1 engine specs and information here is for the stock LS1 engine. 3 small block engine from General Motors used in cars from 1997-2004. Cold working the surface of the Babbitt eliminates micro-fissures that can lead to fatigue failure. LS1 Engine Specs: Performance, Bore & Stroke, Cylinder Heads, Cam Specs & More Posted 10/12/17 by OnAllCylinders Staff Last updated on The LS1 is the original Gen. This hard and high strength condition provides the "toughness" needed for racing applications. By leaving the structure as cast, tensile strength is almost doubled over the standard bearing. By cooling the Babbitt quickly in the casting process, very fine grain structure is achieved. Micro babbitt, a very thin layer of lining which reduces the microscopic deflections that occur to a bearing when loaded and thus increases fatigue life. Camshaft, Mechanical Roller Comp Cams High Pressure Oiled Lifters Non LS. The high performance all-round cam bearings offer more than double the fatigue strength of conventional bearings, withstand racing spring loads, and maintain the excellent surface characteristics of Babbitt.

Pulleys, Front Drive Systems & Accessory Drive Kit Dura-bond CH-10 Camshaft Bearing Set for 1st Gen LS1 Engine Block is manufactured with a thin lining layer which reduces microscopic deflections under load. Main Caps, Main Girdles and Valley Girdles.
