Transformula: So, the bolt pattern is the same on all the medium duty EF transmissions? If I can pick up the bell from a Kodiak or Topkick that had the 454 in it, that had the non-OD transmission I would probably be ok, that is if the mating surface part of all the medium duty EF transmissions are the same. I also saw where you can convert a non-OD EF transmission to an OD transmission by doing a rebuild, and changing some gears. I saw a couple different size input shaft sizes listed, and also 2 different pilot sizes. I think I saw 25mm and 30mm for the pilot. My BIG problem so far is finding out the bolt pattern and finding the right bell for the swap. Anybody out there got the right bell, or know where I can get one? My 454 is a MkIV. The non OD unit with the bell to the 454 I referenced above has been sold, so no luck there. I may even have to see if the flywheel itself was different. Were there different size flywheels in the Chevy trucks with the 454, depending on the transmission/clutch size?
