Short Block Assembly
General Information
The cylinder block is a 60 degree high‐pressure die cast aluminum design with cast steel cylinder liners. The
leading side of the block is on the right side and houses cylinders 1, 3 and 5. The cylinder block is an open deck
design with cut slots between each cylinder. Two knock sensors are located in the block valley. The cylinder
block has three sets of piston cooling jets which are attached to the main oil gallery. The four powdered metal
main bearing caps are a cross‐bolted design and have directional arrows molded into the caps. The number 2
main bearing is the location for the two piece upper half thrust
bearings. The thrust bearings are installed with the oil groves facing outward. The main bearing caps are a 6‐
bolt design and cross‐bolted for improved lower end strength. There are three oil drain back drillings located on
Blocks and crankshafts are precision measured during manufacture and marked with specific bore and journal
size identifications. Bearing shells are manufactured to provide select fit clearances based on these
measurements.
Engines should be kept with their respective parts as select fit clearances will differ between each engine.
Clearances may be confirmed through actual measurements with reference to the following bearing
selection charts and identification markings on the block and crankshaft. See Section 5 Sheet 2
Crankshaft thrust washers are not selectable and are only available in single thickness.
Main bearing fasteners are snug torque plus angle tightening. Main bearing fasteners are Not Yield
Fasteners. Main bearing fasteners have been torqued twice during manufacture. Labs should strive to
minimize the number of torque applications during test build. If threads in the block are pulled during
assembly, the labs are allowed to use thread inserts, however, labs must understand the main caps are
positioned through the shoulder of the fastener and threaded inserts could cause misalignment.
Main Bearing cap bolts are replaced as necessary.
Cylinder head bolts are reused for torque plate application during honing.
Cylinder head bolts are replaced with new fasteners for test build.
Connecting rod cap bolts are replaced for test build.
