POST CODE

 

These HIGH PERFORMANCE components should be checked for suitabilty by the

person installing them as engines of the same group can vary in

valve length spring installed height and collet grooves

IT THE SOLE RESPONSIBILTY OFF THE INSTALLER TO CHECK SUITABILTY

 

 

Can anyone tell me what this cam will be like? I have no idea how to read and translate these sort of things :P

 

Also it's listed as a 3k 4k grind?

Where yours says "advertised valve timing 295deg" mine says "270", and where your lift is 0.4118 & 0.4091, mine is 0.3965....

 

So yours should be quite a sporty high-revving cam. Set the tappets at 14thou like they say, and if you want it revving hgher close them down to 12thou, or a smoother idle open them to 15thou. I found their 16thou recommended gap on mine too wide and the tappets rattled, so I'm running 12thou.
