These 268° cams are perfect for street, strip and track engines with 350-600hp. They work great with E85 and similar ethanol blend fuels, and are suitable for 48-58mm turbo. You'll get improved mid-range power and a broader power band, while still maintaining good throttle response, especially when using MIVEC.

• If you plan to rev up to 8000rpm and boost up to 35psi, we recommend our valve spring KVS63-BTK.
