Bliue dm Posted June 26, 2021 Share Posted June 26, 2021 (edited) I know the timing spec is one the valve cover but I want to know what the experts suggest the timing spec should be on my 97 e7 400?

Bliue dm Posted June 28, 2021 Author Share Posted June 28, 2021 (edited) So don't advance for better running.(more power) like 8 degrees Edited June 28, 2021 by Bliue dm Quote Link to comment https://www.bigmacktrucks.com/topic/67147-e7-engine-timing-spec/#findComment-475976 Share on other sites More sharing options...
Popular Post Vmac3 Posted June 28, 2021 Popular Post Share Posted June 28, 2021 Do not advance the timing, Cylinder pressures can get out of control and may cause harm to the engine. These engines were not known for tons of power, they were known for reliability and adequate power.

theakerstwo Posted June 28, 2021 Share Posted June 28, 2021 I have always went with the ideal of more than 2 degrees of timing is too much.Another way to look at it is would you use someones Specs over the factory which has to stand behind the engine for years and has built many more than any of us. 1 1 Quote glenn akers Link to comment https://www.bigmacktrucks.com/topic/67147-e7-engine-timing-spec/#findComment-476007 Share on other sites More sharing options...
