Need some info on Comp grind XR286R 383-440, solid roller

[AZ Steve]

Id like to get a copy of a cam card if anyone has it. or at least the intake and exhaust centerline. I have all the rest of the cam data. including the LSA. need to verify the information I have. The blue in the Picture is an example of the information I am looking for
Thanks,

Their web site lists the cam specs.

I know, But they don't list the intake centerline and exhaust centerline. as i said i have all the rest. All they give is the LSA. (lobe separation angle)

The XR286R is a solid roller...... this data is for hydraulic rollers:



Aside from that...... what do you think the area circled in blue is telling you?

This is an example of the information I am looking for. My first post has the solid lifter grind I am asking about.

Thanks to everyone,

I will call Comp and find out what the intake lobe center line is and the exhaust lobe center line is for grind
XR286R 383-440,

You say you have the timing events.

If you have those...... then you also have the centerlines.

As posted above-
The intake event is 37/69:
So, 37 + 180 + 69 = 286
286/2 = 143
143 - 37 = 106 ICL


The exhaust event is 80/32:
80 + 180 + 32 = 292
292/2 = 146
146 - 32 = 114 ECL

Thank you Very much!!! for the formula
