What would be the difference if you changed your stock rockers to say 1.8 or a little larger. How does larger rockers affect your horsepower and does it also put more stress on the engine?

 

search 1.8 rockers at the right top of the page, search this forum..

We had one car gain 15rwhp on a bone stock internal car for a total of 380rwhp. These were the Harland Sharp 1.8 ratio rockers. The extra ratio adds to the lift and duration of the stock cam esentually acting like a larger cam. It does put a little extra strain on the valvetrain but if you are not changing cams it will work just fine.
