If you're using bolts on your main caps, use ARP main cap bolts. They feature a generous under head radius, rolled threads and a special heat-treating process that add up to as much as a 1000% longer fatigue life compared to most main cap bolts. They're forged from 8740 chrome-moly steel and each set of bolts comes with parallel ground, hardened steel washers for accurate torque readings.
