For high-performance racing engines making over 800hp, Kelford Cams 270ø/280ø camshafts are a perfect cosideration. For single turbo, opt for 64mm or larger, and for twin turbo, go for 54-58mm. These cams work well with E85 and allow for using the OEM shim on top of the bucket.
- For optimal results we recommend KVS207 valve spring kit for increased performance.
