roller rocker

I've got some 1.7:1 Harland Sharps on the Z, seem to be workin' well. Also I have some Crane's on the Ford, also high quality.

I am fixing to do a 1.7 Scorpion rocker on the truck. They say they are an easy direct bolt on with no mods.
I will let you know how it goes. They should be here tomorrow.

Why are you considering roller rockers on a stock motor? What is your goal? If you are wanting more performance, I would get a tune. If you want more performance than that, get a tune and a cam. Just my two cents.
