4.7.9.6 Camshaft Timing Setting.
Camshaft timing will be set to standard Ford settings by placing camshaft setting bar, Ford no. 303-367, into the
slots at the rear of the camshafts and by pushing fully home pin (as shown in diagram 1), crankshaft timing pin
Ford no. 303-620, to be screwed into the hole at the left rear of the engine block, (as shown in diagram 2), and
by following Ford recommended practice for the setting of camshaft timing.
Diagram 1 Diagram 2
Irish Strykers Racing Championship Regulations 2022 – Published Copy Page 15 of 244.7.9.7 If requested by the Eligibility Scrutineer, a car or cars, as the case might be, will be presented for scrutiny with
the engine rocker cover and crankshaft timing pin blanking plug removed. The timing settings will be checked
and when found to comply, will have the engine rocker cover replaced. TDC setting of the crankshaft may also
be checked by other means to ensure compliance. The two bolts used for sealing the rocker cover must be
tightened to the specified torque. This must be witnessed by the scrutineer, who will then seal the rocker cover.
Any two adjacent bolts can be used. If subsequently, a car needs to have the rocker cover removed at any time
for maintenance purposes, the Championship Eligibility Scrutineer will have to be notified, and the rocker cover
may be resealed in the same manner as described above at Championship Eligibility Scrutineer’s discretion.
If a car is fitted with a different engine to the engine originally presented, the above sealing procedure might
have to be adhered to again at Championship Eligibility Scrutineer’s discretion.
Machining of any parts which can in any way alter this setting is prohibited as already covered elsewhere in the
technical regulations.
If an engine is subsequently found to have different camshaft settings, and the seal has not been tampered with
or broken, it will not be deemed to be in breach of this rule.

4.7.12.4 The crank journals may be reground for reclaim, as long as the minimum crank weight is respected. Standard
oversize and undersize bearings are permitted.
Irish Strykers Racing Championship Regulations 2022 – Published Copy Page 16 of 244.7.13 Flywheel and Clutch
4.7.13 The flywheel assembly must be a standard component. The unit may be reduced in weight according to the
diagram below. No other machining is allowed. To achieve minimum weight and balance, material may be
removed from the area indicated on the drawing. For rectification the clutch mating face may be resurfaced,
provided the minimum weight is respected. It is permitted to use a similar pattern replacement clutch (i.e.,
conventional single diaphragm spring) and driven plate with shock absorber springs (four or more spring
assemblies). Organic friction material only is permitted. It is permitted to alter the clutch spline to suit the
gearbox. Racing clutches are prohibited. The position of the ignition timing mark on the flywheel relative to the
crankshaft sensor must remain within Ford design limits at all times. No part of these regulations allows this to
be altered. Also the electronics regulations specifically ban any change that could in any way alter the ignition
timing as defined by the standard calibration within the engine electronics.
