SBC 400 How would this cam work?

probably sound fast as hell. issues here- are the springs compatible?(coil bind,etc.) what type trans or converter?(wont make much torque under 2600).how much compression?(cams this size bleed off alot of cylinder pressure). gear ratio? weight?also you wont be able to turn a stock bottom end 7000 for long. if you can leave the line or come off the corners at around 3000 and the springs that you have are good for 6000-7000 you may end up with what you are looking for.
