These 282° high HP solid lifter racing cams are perfect for well-built time attack and drag racing engines that are capable of producing over 700hp with a 62mm+ turbo. They perform exceptionally well with E85 and similar ethanol blend fuels. However, OEM hydraulic lifters won't work; you must convert to solid lifter.

• To achieve up to 9000rpm and 40psi boost, Kelford Cams recommends pairing these cams with valve spring KVS63-EXTREME.
