Rocker arm ratio for a 3.0 V-6??

[Fredness]

I'm working on a modification to the rocker arms on a 3.0 V-6, but for specific numbers (Horse Power, Friction, timing effecs), I need to know the rocker arm ratio for this motor. Local Ford dealers are useless, Help!

The ratio for the 4.0 is nominal 1.46:1- actual will vary a bit. If your looking for a 3.0 l I have no Idea- Explorer never came with a 3.0l engine.

Hope that helped a little.

The 3.0l Rocker Arm ratio is 1.61:1

3.0l is the 60 degree v-6 VIN code U

Thanks

Got confirmation from ford as well, they quote 1.6 +/- due to machining tolerances. Thanks! Fred
