Stage 2 is where the real upgrades start. 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 and Kelford or GSC cams instead of a stock valvetrain. 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.

It 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. Either way it comes back ready to run once it's through break-in.
