FLuttering noise from gas engine

[SGrady]

I have a 2001 2500 gasser w/the 360 V8. Under excelleration I can hear a faint fluttering noise coming from the engine. Wondering what it could be, maybe some kind of vacuum leak? Any thoughts appreciated.

You may try checking the airbox. I'm not sure if the gassers have the snorkel that goes through the airbox into the fender well or not, but if it does, that can cause some strange noises, usually under high air flow conditions. Try removing the snorkel (it's easy to slip out) and see if that helps.
