I’m having one hell of a time with my Lincoln. Got a 430, and my exhaust system is totally shot. I don’t know of I should replace the stock manifolds with headers or what. And now here’s the real bit…I have all matching numbers on the car. So I don’t want to change anything, but don’t know a good method to repair the original exhaust.
Also, I don’t think my alternator is going, however my amp gauge fluctuates a lot, and my headlights/interior lights get 2-3x brighter when I rev the engine. Any help is appreciated.
There are some good choices for the exhaust system. A good professional exhaust technician at your location should be able to build you a real nice quiet system with mufflers and resonators as is required for these engines. If you are keeping the car and it is a nice car you could consider a bolt on complete stainless system complete with proper flanges and bends. These stainless systems usually come with a lifetime guarantee and should remain leak free and quiet for the life of the car. If you want to install headers or any type of a loud or modified system you will need to discuss this with that type of specialty exhaust supplier.
The 64/65 lincoln charging and amp gauge circuits are known to sometimes be a problem area. Much of the vehicles electrical power flows through the amp gauge and a bad connection or failure in this area can lead to severe unwanted issues.
