New components may not help much if the distributer is worn badly. Years ago I bought points, etc,. for my \6 and it still ran poorly. A reman'd distributer came with all those parts. Result was like dipping the old girl in the fountain of youth.
Valve adjust, carb kit, and everything else had had done didn't make nearly as much differnce as the distributer. My .02 Hope it helps
