Macktruckman Posted February 12 Share Posted February 12 (edited) The early full mechanical E7-400 injection timing is 19° advance factory. The VMAC 400 is 6°. Im doing the same thing. EM6 finally laid down and I bought a 95 E7-400 VMAC and then a mechanical pump and had antrim build the pump and im in the process of getting it back together. I spill timed mine yesterday at 20°.

Macktruckman Posted April 22 Share Posted April 22 Did you ever decide on a timing setting and how does it run? Quote Link to comment https://www.bigmacktrucks.com/topic/75108-e7-v-mac-to-mechanical/#findComment-574265 Share on other sites More sharing options...
