If you're already looking at cams and valves for a Stage 1, you're better off here, since Stage 2 isn't a-la-carte parts stacked on a lower tier, it's a complete step up in what the bottom end and head can survive. Rods move to BC I-Beam, stronger under load and built to hold more power. Pistons step up to a higher rated CP-Carrillo spec, and the head gets actual GSC intake and exhaust valves instead of just springs and seals. We also machine the block in-house to accept oversized ARP studs at this stage, standard hardware doesn't cut it once you're pushing this far past factory.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eIt is built to safely support tuning up to 1,200 WHP, not a promise that your engine makes 1,200 WHP out of the box. Send us your engine or buy a core from us and we build the whole thing start to finish.
