Not overkill. We went to 1.14" MP bars in my son's 383/4sp '67 Barracuda fastback. With KYB shocks I didn't feel that it was too harsh to ride in. I wish I had kept the .990" bars we had in his car to start with (sold 'em for way too little) for my Barracuda convertible. As it is, unless something changes I'll keep the factory big block bars that I have in it.
