You've probably heard many a horror story about someone loosing an engine when the oil pump fell off and into the pan because of a broken oil pump bolt. Well, you can put your mind at ease when using ARP's premium grade oil pump bolt and stud kits. You have a choice of black oxide finished 8740 Chrome-moly steel or low maintenence stainless steel. Both are nominally rated at 170,000 psi tensile strength to give you plenty of clamping force. Also take your pick of 6 or 12 point heads. This is insurance that no conscientious engine builder should be without! The studs come with flat washers and nuts while the Ford kit has bolts and washers.
