I would recommend that you use the CLEVITE 'H' series main bearing set, not the 'HG' set, in most high performance applications as the edges are beveled for crank clearance and the material is designed for high loads and only the upper half of the main bearing is grooved.keep in mind its the pressurized oil film that keeps the crank and bearing surfaces from touching and wearing so every effort to maintain that oil film must be made and clearances are critical to maintaining that oil flow
The CLEVITE HG shells have 360 degree oil grooves,with both the upper and lower shells being grooved, they can,t maintain the same loads as the surface support area under the crank in the main caps are smaller. The H series main bearings have only the top shells grooved and this all that is required in any high load application. The fully grooved bearings tend to cause bearing failures, as the reduced bearing surface in the lower load carrying bearing even with the increased oil flow can,t prevent the crank from wearing the lower bearing surface at high loads at high rpms
MAJOR CAUSES OF PREMATURE BEARING FAILURE
Dirt ......................................... 45.4%
Misassembly .......................... 12.8%
Misalignment .......................... 12.6%
Insufficient Lubrication.............11.4%
Overloading .............................. 8.1%
Corrosion ................................ .3.7%
Improper Journal Finish ............ 3.2%
Other ....................................... .2.8%
