The car hobby is all about tinkering and modifying. I say yes do it. You know it wont be like adding 100hp but many many mods are done to old and new cars that do not necessarily increase power. Big ole Accel super coils, 8mm plug wires- aftermarket electronic distributors and ignitions, chrome valve covers Moroso chrome air cleaner etc did not make more power on old iron but they were fun to install and look fantastic!
