Kelford Cams recommends using their Stage 3 drag racing cams for S58 engines that are professionally built and capable of making over 1400hp. If you plan on using high boost and 76mm+ turbo sizing, then you should be using either ethanol blend or methanol fuel.
- It’s important to upgrade your valve springs, KVS58-BT is the recommended option.
- Additionally, please double-check clearance for the new racing cam lobe with your intake intermediate rockers.
- If you’re using OEM pressed steel rockers, be sure to deburr them to avoid any issues with fouling on the larger cam lobe.
