This Stage 3 camshaft set from Kelford Cams is a drag racing profile for professionally built BMW S58 engines. It has a 298/292 degree profile with 10.40mm/10.80mm valve lift and is aimed at engines making 1400hp or more, with turbo sizing of 76mm or larger on high boost, running an ethanol blend or methanol. Kelford states it is for professionally built engines only and requires a valve spring upgrade, recommending spring KVS58-BT. Kelford also asks that the clearance between the new cam lobe and the intake intermediate rockers be checked, because the sharp edges on OEM pressed steel rockers may foul.
