 The ARP main studs are greased...  The ARP main studs are greased with assembly lube, and the nuts secure the cam with the previously mentioned torque specs. The crank mains are measured individually with calipers, and the calipers are used to zero the bore gauge (for the highest degree of accuracy possible). Then the bore gauge will indicate whether a thicker bearing is needed;... |  ...however, the precise machining...  ...however, the precise machining of both the block and crank negate any compensation in this case, as clearance is consistently between .0024 and .0026. The Clevite 77 main bearings are treated to Lubriplate assembly lube before the crank is dropped in and the mains are given their final torque.... |  ...These H-series bearings...  ...These H-series bearings are perfect for medium- to high-rpm engines like LS1s, and were developed with a tapered or eccentric design primarily for NASCAR. A measured .0045-inch endplay is observed with the crank, which is perfectly acceptable. |
 A Manley LS2 double-roller...  A Manley LS2 double-roller timing set is used for the high-spinning motor, the crank gear is hammered on,... |  ...and the main gear is slid...  ...and the main gear is slid on with the chain attached. The gear bolts require 18 lb-ft of torque. |  The bores and piston skirts...  The bores and piston skirts are coated with assembly grease to ease the process of inserting the pistons and attached rods.... |
 ...The rod bolts are torqued...  ...The rod bolts are torqued to spec, and then it's time to check the clearances. |  One of the reasons Golen uses...  One of the reasons Golen uses the Compstar rods is because the 2-inch rod journals (stock is 2.100-inches) increase block clearance by pulling the long 4-inch stroke closer to the center of the bore.... |  ...This negates the need to...  ...This negates the need to grind the block for rod clearance. The exterior girth is also much slimmer compared to several other top manufacturers the shop previously tested (by between .073 inch and .505 inch). Deflection is inevitable in the rotating assembly, so every little bit of clearance helps. |
