The top main cap bolts are torqued in place in the proper sequence to ARP’s specs.
The cross bolts are also torqued in the correct sequence. An LS has six bolts per main cap for the ultimate in bottom end stiffness. Old small-block Chevys only had two and some were modified for 4 bolts. With the mains secured to the main bold of the block from the top and to the deep and stiff block skirts on the side of the block, the LS has a very strong and stiff bottom end.
Next Howard drops the King XP rod bearings shells into the rod and the rod cap. Like the crank, the Eagle rods have the optional ESP armor surface finish. The super slippery finish really reduces windage loss and frees up several horsepower.
The rod caps are tightened and torqued to final tightness so the bores can be measured.
Like the main bores, the rod bores are measured in three places across and three places around the rod bore. Once the bore size is determined, the rods can be matched to the crank rod journals for best fit and different sized bearing shells can be mixed and matched to get the desired bearing clearance.
