0 alex g Posted August 10, 2016 Share Posted August 10, 2016 Depending on what your plans are I'd give it a tuneup including setting top end and possibly injectors before I'd turn things up. I'll be cheaper in the long run Sent from my SM-G386W using Tapatalk Quote Link to comment https://www.bigmacktrucks.com/topic/46398-350-e7/#findComment-341899 Share on other sites More sharing options...
0 Mackpro Posted August 12, 2016 Share Posted August 12, 2016 1999 Etechs can be bumped to a 400 with a download at the dealer. No hard parts. However they like for you to install the bigger vibration damper. Any thing bumping Etechs that are 350/400 up to 427 or 460 require turbo and injectors and cam shaft key way replacement to keep from overheating. This is for the 1999- 2001 ETECH engines, the 2002 CCRS ETECHs and ASETs all have straight camshaft keyways regardless of HP. You could go with some aftermarket injectors and turbo and skip the dealer all togethhttps://www.rochesterdiesel.com/store/medium-heavy-duty-trucks/mack/97-06-e7/mack-performance-injectorser.
