I've been looking at building a 393 for my 93 Bronco. I was wondering if my E4OD would hold up to this or not and what all would I have to have done to it. If I have to go to a C6 I'm just going to trash the idea.

 

I would get an AOD from Artcar or some other performance tranny builder because the its not that the e40d might handle that but the fact that you must go to mass air to run the 393 motor and a kit to do this will cost $1500 because of the e40d.

 

how do i find out if i have mass air?

 

you will have dual tubes that go into one with a sensor right before the airbox
