The bottom end gets a billet crankshaft and KLM billet main caps held down with ARP 625 main studs. HD sleeves come standard instead of as an add-on. Up top, the Extreme Fire-Lock head gasket, billet head dowels and ARP 625 head studs keep the head sealed, clamped and located, and our Anti Slip Cam Gear Upgrade keeps cam timing where we set it.\u003c\/p\u003e\n\u003cp\u003eIt is built to safely support tuning up to 1,800 WHP, not a promise that your engine makes 1,800 WHP out of the box.
