I tried to find if it had been covered before in here but there are just so many posts of different subjects and everything, after an hour I decided to make my own. I was talking about between the gas motors and the diesel in the superduties. I know the V8 and the V10 have the same one, and you are right, a V10 shares the same bore and stroke as the V8. If it helps at all the diesel engines share the same bolt pattern as the older 385 series block (370,429,460).

See what I'm trying to do is I have a good running 5.9 Cummins at my disposal, and I have a 5.4 that is dieing a slow painful death. So when the 5.4 finally dumps out I was thinking about trying to put that Cummins in there. I've seen a few of these done but I was wondering if I was going to have to try to find a transmission also. Hmmmmm......
