Kelford Cams 280° racing camshafts are perfect for engines equipped with 64mm-72mm turbos and provide the best performance at high rpm power and wide-open throttle. They are designed to work great with E85 and do not require any cylinder head clearancing.
To ensure optimal performance, Kelford Cams recommends using valve spring KVS20 (for non-NVCS heads) or KVS25R (for NVCS heads).
