I was also looking at these shaft rockers from Hughes. I currently have stock magnum heads with the factory pedestal mounts and Hughes 1110 springs. My cam has .507/.514 lift. With these 1.65 ratio rocks my lift would go to .523/.530 according to my math looking at my lobe lift from my cam card.
I just wonder if that would be pushing it lift wise on the stock mag heads and 1110 springs. The op might be pushing it too with the cam they used in the 380 crate? Not trying to high jack just wondering. Any thoughts?
