Looks like you'll be able to order the 5% ZR2 production with a Callaway supercharger upgrade that takes the 6.2l to 602 hp and 560 lb-ft of torque. No word on whether you can have it retroactively installed... it does come with a 3yr/36K mile warranty. Starts at $25K ![Eek! :eek: :eek:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
