Hi
I have bought "RS-Cams" from EBS Racing but never got proper cam timing instruction, even after many emails
So I tested these cams and also original cam at local "cam doctor".

Can you say from this picture that what are proper cam timing settings?
Is it 1.8mm at overlap when lash is set to 0?
Thanks for you help!

Since you have the measurements, I would determine the proper lobe center and use a degree wheel to install the cam rather than the "lift at TDC" method.

 

Geoffrey: Could you give shortly instruction for that timing method. I understand how to calculate those lobe centers and I have good degree wheel but what then?

 

Install the cam with no rockers
Use a piston stop or dial indicator to determine TDC of #1
Install degree wheel at 0 (TDC)
Rotate the engine to the desired lobe center
Install cyl #1 intake rocker arm and set lash appropriately
Install dial indicator on valve spring retainer - NOT rocker
Rough in the cam by rotating until the dial indicator shows max lift (be careful you don't hit piston with the valve)
Lock cam in
Set dial indicator to '0' for max lift
Select a lift value, say .050"
rotate the engine backwards until the dial indicator shows .100"
rotate the engine forward until the dial indicator shows .050"
note the degree on your wheel
rotate the engine forward, past TDC until the dial indicator shows .050"
note the degree on your wheel
the degree at the mid point is your lobe center.
adjust accrodingly until you get the cam to your desired lobe center.
install remaining rocker arms.

Repeate for bank 4-5-6 using #4 rather than #1
