There are a lot of things to consider when spinning a 289/302 above 7000. And how fast will it spin up to that RPM level. Weight removal in the rotating assembly, and removal of any drag like using a windage tray, strenght by adding a main girdle support, light weight rods, slugs and lifters allow you to RPM quicker and higher. The cam choice to determine the power band, along with the intake and carb. Also take into consideration the valve springs, stock springs will usually start the valves floating around 6000 RPM. My max power is made between 7000-7600, and the engine was designed to make power in that range, since it leaves at 4800. 8500 on a stock 289??
