StoneandSteel Posted 4 hours ago Share Posted 4 hours ago My 2007 Mack CV713 engine has AI400 and 2006 on the valve cover id tag. My question is: are the AI400 and an E7 the same engines in 2006 if you were swapping the engine assembly out? My vin number shows that I have an E7 from the Mack dealership. Any help would be appreciated. Quote Link to comment https://www.bigmacktrucks.com/topic/74778-2006-ai400-or-e7/ Share on other sites More sharing options...
