Want to improve ignition....

hey everyone! While waiting for my springs and torsion bars to come in the mail I was pondering ignitions. Obviously I could get an MSD, but I feel like that is overkill on the street. I wanted to know if anyone has any suggestions to whether or not it is overkill, or if I should be looking at just a newer ignition with coil and cap and rotor. I am interested to hear what you wise sages have to say! Thanks!

Let me know your thoughts!!
