General FAQ

From how long have we been in business? to How should I run my new Kent Camshaft in? this is where we answer your most common questions.

How do I choose the right cam?

This is probably one of the most difficult choices you will have to make - some people rely on the help of an experienced engine builder whilst others use books and internet resources, however we at Kent Cams have exceptional experience in cam profile choice and have a technical department with more experience than any other UK cam producer.

Check list

  1. What is my intended application? - road, track day car, rally, race etc.
  2. Maximum and minimum required engine speed range? - within the design limits of your pistons, crank and con rods.
  3. What induction and exhaust system are you using? - Carbs, injection, forced induction.

With answers to the above we can start to guide you in the right direction please feel free to either e-mail or telephone us for further assistance.


What is 'Lift at top dead centre' cam timing?

With the proliferation of multi valve/multi cam engines the full lift method can be a labourious hit and miss affair. This is solved by setting all of your camshaft timing at a specified lift at the datum of TDC.

This Method has been in use by Kent Cams and many top engine builders for many years. This method is relative simple and has the benefit of setting individual cams at the same position without resorting to excessive crankshaft rotation.

For example the Ford x/flow camshaft 234 has a quoted 'TDC' lift of 2.84mm. This means that when the piston is at overlap top dead centre (not the firing TDC) the cam should be set so that the inlet valve has 2.84mm of lift.


What is 'Full lift' cam timing method?

For many years the most commonly used method has involved establishing top dead center (TDC) as a datum (zero degrees) and positioning your camshaft with its inlet valve at maximum lift at a given position relative to this datum.

For example take our Ford x/flow camshaft number 234 which has a quoted figure of inlet timing @ full lift = 103 degrees. This means that the inlet valve should be set to be fully open at 103 degrees after top dead center. Therefore using a protractor or timing disc you can establish 103 degrees after TDC and it is at this point that your inlet valve should be fully open. Minor adjustments from the standard timing point can be made with the aid of adjustable timing kits or an offset dowel.


If in doubt what should I do?

If you are in any doubt on any camshaft related subject whether it be cam timing, valve to piston clearence or oil pressure do not attempt to start your engine call us first - we don't bite. 

How do I run in my new cam?

As a general rule it is important to ensure good oil flow during the camshafts first 20 minutes of life. Consequently it is essential to run the engine at a fast idle (above 2000 rpm) to ensure adequate lubrication of the camshaft and followers. This will allow the surfaces of the cam lobes and followers to bed in properly and guarantee long component life.


How long have we been producing performance cams?

Unlike other cam manufacturers we at Kent Camshafts specifaclly started our business to produce the most cost effective, reliable and performance driven cams. We have been producing performance cams and custom grinds for over 30 years.
