These high-performance racing cams are specifically designed for well-built time attack and drag racing engines that pack a punch, delivering over 700hp and running a turbo of 62mm or larger. Ideal for E85 fuel and other ethanol-based blends. It is important to note that these cams are not suitable for OEM hydraulic lifters, and a conversion to solid lifters is necessary.

• For those looking to reach up to 9000rpm and a boost of 40psi, Kelford Cams highly recommend using valve spring KVS63-EXTREME.
