Re: Roller Rockers

Whatever rockers you can afford. You don't have a lot of lift to need anything special.

That looks like some sort of power adder cam with the long duration and short lift.

Re: Roller Rockers

Re: Roller Rockers

1.6 rockers would be pushing the limits of the stock springs. It's still under .500 lift but it's getting close.
