It is very important to locate true “TDC” to accurately set camshaft timing. After
locating “TDC”, rotate the flywheel assembly clockwise until the front intake lifter is on
the heel of the camshaft (lowest point of travel), place the dial indicator in position with
the front intake lifter, with the axis of the dial indicator in line with the front lifter axis
and zero the indicator dial. You will be checking the front intake closing event. Slowly
rotate the flywheel assembly forward until you arrive at maximum lifter lift, and then
continue to slowly rotate the flywheel assembly clockwise until the dial indicator reads
.053” or the specification that the manufacturer has stated. Now check the position of the
degree wheel and note the degrees at this position. The reading on the degree wheel
indicates the timing of the front intake closing event in crankshaft degrees. This should
correlate to the closing specifications stated by the camshaft manufacturer. If the
measurements do not match that of the manufacturer, camshaft timing can be modified by
pressing the drive gear from the camshaft and indexing it to achieve the correct timing
event … care must be take in doing this or irreparable damage can be done to the
camshaft and gear. If the camshaft drive gear is moved it is imperative that the timing
event be rechecked or severe engine damage can occur.

Special note
– Only rotate the flywheel assembly clockwise, do not change direction
of rotation during the camshaft timing exercise. Changing rotation direction can result in
erroneous readings due to backlash in the camshaft and pinion gears.
As stated earlier in this section, for “street” application this is not a crucial issue, and
+/- 2 degrees is a very acceptable number, but for all out race engines this is a very
important process with no room for variance.
