ARP Main Cap Bolt kit 140-5001 (discontinued part number)
ARP propoganda (edited 'cause you don't want to read all that fluff): ARP High Performance Series main bolts are rated at 170,000 psi (the replacement part 140-5003 has a 190,000 psi rating with all the other specs the same); forged from 8740 chromoly steel and feature a reduced wrenching head, large underhead radius, and rolled threads. The threads are rolled after heat-treating which gives them about 2,000 percent better fatigue strength than most main bolts that are threaded prior to heat-treating. Hardened parallel-ground washers are included.
$49 plus no tax and free shipping. PayPal F&F (add 3.6% for Goods/Services) or postal money order.
