* N.B. These figures relate to a 2.0 litre engine.
Power peaks and operating range will change with alternative capacities.

BHP / litre figures should be multiplied by engine capacity to arrive at feasible power targets;
i.e Type 4011C camshaft in a 2.1 litre engine would be:- 88*2.1 = 184.8 BHP.

N.B. Some profiles are not suitable for use with automatic gearboxes.
New followers must always be used. Valve timings and lifts, where shown, are for guidance only.
Use data sheet supplied with camshaft, together with standard timing marks.
HOLBAY TORNADO camshafts have no need for a vernier timing pulley.
