I'm building a 4.10 geared car and was wondering how to get the 440 to live at 3500-4500 rpm when I drive it to cruise-ins or car shows? I don't usually drive more than 2 hours to a show or cruise-in. For those times I do drive at highway speeds it will put the engine RPM in that range for an hour or so. How do you build a 440 to spin those RPM's and live?
