I just put a set of Konis on my '70 'cuda. They're adjustable for your own comfort level or driving style ... mine are set pretty stiff for the street because of all the front end weight of the big block, but I adjust them to soft for the drag strip for weight transfer. Konis are expensive, but not more than $25 - $50 more than another decent brand. Beware of the rear mounting stud though. There are two sizes and the Konis only fit the smaller. The larger size is 11/16" and requires drilling the shock's bushing with a drill press.
