mackrmodel686st Posted 14 hours ago Share Posted 14 hours ago Does any one know what it would take to convert a 400 vmac iii to a 427? Turbo, Injectors, computer. Anything I might be missing?

Joey Mack Posted 2 hours ago Share Posted 2 hours ago The early e-techs use an offset cam key in low and high HP engines. You would flip the key one way or the other for the desired HP. In your case Inexpect you have this key. The cam shaft has to come out to do this. After that, nozzles, turbo, and data file should get you what you want. If you have a CCRS engine the cam key is left alone Quote Link to comment https://www.bigmacktrucks.com/topic/76692-400-to-427-conversion/#findComment-596414 Share on other sites More sharing options...
