Not so fast.  There are a lot of  things that can cause the failure of one cylinder, usually dirt in the carbs.  Start with the inexpensive options first.

BTW, you'd do better to post this in the Technical Help forum.  The Turbo guys probably won't take much interest in your '80 Custom.

Checking for corrosion inside the plug caps is an even easier way to start looking for the cause of "one cylinder" operation - just exchanging caps can sort out a "possible".
