The Chevrolet LS V8 has, without doubt, become one of the most popular performance engine platforms ever produced. Chevrolet used all their experience in producing the Small Block Chev V8 and applied that to their new generation of LS V8’s released in 1997. The LS is a common performance conversion, thanks to its compact size, relative affordability and availability of performance parts, and can be found in almost any type of vehicle and many different forms of motor racing. Bennett Motorsports, Pontiac GXP, 427 LS, Twin-turbo.

LS Application Guide

5M7298H
The most popular main bearing set. 5M7298H has extended grooving – a full 180° groove in the upper half,
with a matching partial groove in the lower. This provides improved oil supply to the conrod. The tapered
runout of the lower partial groove smooths big end supply cut-off avoiding pressure pulsing and cavitation.

5M7299H
This set is the same as 5M7298H in all aspects except for the grooving. The shells in this set feature shortened
grooving, with a plain lower half and a shorter upper half groove of approximately 120°. This set is an option for
engine builders looking to moderate oil flows and/or balance supply between the rod and main bearings.

Calico Coated
ACL also offers all of the above parts in our Calico Coated range, these are coated by Calico with their premier
CT-1 dry film lubricant. Part numbers that are Calico Coated are designated by a C suffix in addition to the
usual suffixes of the base set, ie 8B663HC-STD.
