I have a points distributor rebuilt and curved for my car done by Suntuned. After talking to him if your rpms don't exceed 6000 rpm a points distributor will be as accurate as any of the others. He also builds them with NOS points which are better than anything from the aftermarket. Distributor with cap of my choice curved for my car was around 90.00. The cars idle is smoother and pulls stronger than it ever did.
