I need to know what the bell housing bolt pattern is on a 7.3 PSD. I want to make an adapter so that I can bolt a 4r100 behind a 5.9 12v cummins. I have tried looking everywhere for this info, and I can't find it, maybe some one has a bare block around Philadelphia that I could borrow and take to a machine shop and have measured, or maybe you have the specs already, please help me out here, I know they make adapters, but they are really $$$$$$$ and I have heard many horror stories about them not being quite right, I have already priced out what it would cost with a local machine shop and it is looking like it might work out better to do it my way, thank you in advance.

 

destroke.com has just a thing..Jeremy is doing a destroke... have a look..you will find your answer in there..or maybe he could help you with what you need..

Pull the adaptor plate off a 6.9 or 7.3. Use the trans holes to make new plate,or drill new hole in that on for the cumapart. The E4OD and C6 have the same bolt partern as the 4R100 due to the powerstroke started out with the E4OD.

 

I can understand the money thing, but as far as fit goes, I can tell you that the Destroked adapter plate is top notch. There are absoutley zero issues with fit on that plate. Everything bolted up just as it should, both to the block and the transmission to the plate. Nothing was at all was not in alignment, even by just a little bit. It fit perfectly. Scott at Destroked makes some first class pieces.

 

Fwiw, I believe the pattern is the same as a 460ci.

 

FWIW, I know that's wrong.

 

Man that's an old thread from 2008.
