When building each of our Shootout engines, we've relied upon ARP engine building kits for the majority of our hardware. We're really addicted to these sets, since they offer all of the hard-to-find hardware in organized packages for each part of your engine. In addition to the organized approach, these are top-quality stainless steel ARP fasteners, so you're getting durability along with the easier assembly. Nice! Our big-block Ford kit carries PN 555-9601.
