could it be lean?

Bill I think your on to something.It may be too lean since he passing so much air through that 1150 and max jet is #100 or .125. Try a 1050.



I'm no expert by a long shot but sounds like either a lean condition or eletronics problem. I had the same thing happen to a 383 dart pulled like a mofo thru 2nd then would stumble down track. Jetted up by 2 until the problem was sovled.
