genoredstar Posted December 16, 2023 Share Posted December 16, 2023 Have an E7460 v mac 3 motor, If i change the cam out and exhaust manifold can this work? thinking I may need to change lifters as well as push tubes. Use my eups, injectors and turbo? Quote Link to comment Share on other sites More sharing options...
880joe Posted December 16, 2023 Share Posted December 16, 2023 Just curious is there a reason for wanting to go to an AI engine instead of keeping what you already have? 1 Quote Link to comment Share on other sites More sharing options...
Adkat Posted December 16, 2023 Share Posted December 16, 2023 Joe, think he wants to convert an AI motor back to etech. Seems like a lot of work, whats wrong with your engine? If you're going to all the effort to pull the cam, wouldn't it be easier just to rebuild what you've already got? Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted December 16, 2023 Share Posted December 16, 2023 I lean towards keeping it and E-Tech.... The cam and the cam key are different, no big deal, the pushrods may all be 417 rods.. yes,,, the engine brake in the AI is much better than the Jacob's 690 set-up... the lifters need to be steel,, ( my opinion only) I dont like the ceramic ones.. Maybe you can post more details about the bad engine, and why its bad.. Pictures help a bunch too.. Jojo Quote Link to comment Share on other sites More sharing options...
JoeH Posted December 16, 2023 Share Posted December 16, 2023 The AI motors are also vmac III so I don't really see any reason you can't. Sounds like you more or less know the major differences between them. Years make a mild difference, early etechs had the EECU under the turbo. 2001 they moved it to the other side.

genoredstar Posted December 17, 2023 Author Share Posted December 17, 2023 Seen a unused remack engine at auction, might be cheaper to do some swapping as opposed to going through my entire engine, such is the reason 1 Quote Link to comment Share on other sites More sharing options...
