284/278 cams for NA racing engines with increased compression, mildly ported cylinder head and well designed intake and exhaust system. More top end power than the 194-B cam, pulling to around 9-9.5k rpm depending on engine. Great for circuit racing or rally with close ratio gearbox. Can still retain VVT on intake, or use adjustable gears for fixed timing. Kelford Cams recommends KVS51-B valve spring.
