VE Rocker Ratios?
I'm trying to find these, does anybody here know them please?

I wish I knew. I am interested to know as well. The rocker ratio changes from the middle rocker as well I think.

low rocker ratio is 1.60, can't find the high rocker ratio.

what is a rocker ratio...?

Rocker Ratio effects how fast the valve responds to change in camshaft diameter. Simply put, it is the relationship between the camshaft and the rocker pad. This of course is altered by changing out the rocker pad to provide a different ratio.

Intake cam:
Primary Lube 5.35mm lift
Secondary Lube 6.64mm lift

Primary Valve Lift 8.52mm Lift
Secondary Valve Lift 10.78mm Lift

Base circle clearence 0.2mm

Primary Intake Rocker Ratio = 1.62
Secondary Intake Rocker Ratio = 1.65

Exhaust Cam:

Pri Lube 4.51mm
Sec Lube 6.68mm

Pri Valve Lift 6.69mm
Sec Valve Lift 10.36mm

Base Circle Clearence = 0.3mm

Pri Rocker ratio = 1.549
Sec Rocker Ratio = 1.595

This is info that I've measured and none is thumbsuck!!

Thanks very much guys (especially Derm), great to get that info.

Just one question for the noob I still am. The higher the ratio the more lift correct? I am just wondering... VET cams have the same lobes for both sides. 11.3mm lift. But if you switch the cam solenoid anyway is it going to increase the lift at all?

Can anyone clarify this info?
