Mack superdog Posted April 11, 2022 Share Posted April 11, 2022 I have an 89 4 valve e6 350 that has a dynatard I’m looking to put jakes on it I have a 2000 e7 electronic engine laying around will the jakes bolt right up or are they totally different Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted April 11, 2022 Share Posted April 11, 2022 the e-7 is a different set up. I believe the bolt hole are a different size, the jacobs 690 heads, have a larger hole and the bolts are shoulderd to fit in the hole, and they are metric thread, and the adjuster on the e-6 uses a fork to set jake lash based on turbo type, the e-7 uses a .015 feeler gauge, or .017, or .021 depending on the updates that were done to the jake heads,, and I think there is only 3 bolts holding the e-6 engine brake head down, where the e-7 uses 6...... I'm curious.... Jojo 1 Quote Link to comment Share on other sites More sharing options...
eveready Posted April 13, 2022 Share Posted April 13, 2022 I have Jake's for a 4 valve e6. Changed out the engine to a e7, kept the e6. Quote Link to comment Share on other sites More sharing options...
