7 Mark suggests never bottoming out the studs, which can crack the block when torqued. Instead, get studs within 1/8-inch of bottom with clean lubricated threads. Then install main caps and torque the nuts one cap at a time beginning at #3. Torque caps in one-third values, checking the crankshaft for freedom of rotation with each cap. If you can't move the crank with your fingertips, something is wrong with the clearance.
