I would like more information on just what you did to fix the problem with your truck. I have had a similar problem with my 86 318 since I got it in 2005. I just figured it was part of the Carter BBD/Holley 2BBL curse. I've owned several 318's during the past 30 years and they have all had that stumble/hesitation. I hate those $*#@&! carbs! Eliminating the computer on my truck helped a little, but it still bogs down. If I had the money, I would throw a 4bbl on it in a heartbeat.
