Thread: EFI= Extremely Frustrated Injection

A really lean condition and retarded timing will give you the same results, hot headers. I have had my headers glowing red hot with my 400. The more I richened up the carb the cooler they got. On the other hand, I have heard where other guys have had really rich setups that caused similar problems. Check and make sure it isn't your timing, and make sure it isn't too lean or rich as well. What do the spark plugs look like?

a rich mixture / retarded timing will move the fire from the cyclinder to your headers. just like harleys you have to keep the fire in the cyclinder. i'm dumber than a tree stump on injection but only one thing burns headers. heat in the wrong spot. i run all my cars lean and do not burn up headers.
