I'm with ya on the inline 6 4 Stroke idea. The 8.3 can be a sweetheart setup and parts are readily available. That is the biggest problem with the 555, they are bummer to round up good parts. They were used in marine applications and that is where most of the core parts can be obtained from. The 903 cousin was used a lot by the US military and in a lot of dump trucks. If someone can do the 8.3 for a reasonable cost, which when I checked, the running gear could be had reasonable, there will be a few others standing in line for the same set-up. In my search I ran across at least two retired rear engine school buses that had super low remans in them crying for a Luxury Coach Lifestyle. We are on the same page here. I'm really surprised many others have not done this. It just takes someone to show it being done and it becomes an infection.
