Rocker Arms

[Robby1870]

Hey, does anyone know the stock rocker arm ratio for a 3.1L MPFI?? And, where could I go about finding performance rockers if they are made?? Any ideas or info would be great.

Im almost certain it's a 1.52:1 ratio

I would assume the rocker arms used in the 2.8, 3.1, 3100 are the same as say, a Chevy v8, but I could be wrong. I knew a guy a long time ago at work that had changed t0 1.6 rockers and stuck a 50shot NoS kit on his Barreta GT with a 2.8L.
