Looks like Cummins. Of some sort.
That is quite a project.

Thanks Jeff, The engines are Cummins 555. Not my first choice but they only have 900 hours on them and(knock on wood) they run good. Cummins are cheap to fix and you can get parts anywhere.

Very cool! Can't wait to see more pics of the progress.
