These 282° high HP solid lifter racing cams are designed for well-built time attack and drag racing engines that deliver 700hp or more with 62mm+ turbo. They work exceptionally well with E85 and similar ethanol blend fuels, generating a broader power band and improved throttle response when using MIVEC. However, these cams are not suitable for OEM hydraulic lifters and instead require a conversion to solid lifter.

• If you plan to rev up to 9000rpm and have 40psi boost, Kelford Cams recommend using valve spring KVS63-EXTREME.
