Just not interested in a diesel for this. Maybe in a future project, but it doesn't really fit into what I do with the truck. If I did something modern like that it would be a 496 big block. I had one of those in a 2500 suburban a few years back and loved it. Tons of torque.
I will stay with something that is close to time period correct and not a V8 and is gas. Those are my two big stipulations!
Just about leaves me with a 261 or something big from a commercial vehicle line like the Seagrave V12 I was and may still be considering! Just seems interesting enough to make it work. Will see what pops up in the next month or two. I hope to get something soon and bring it into my shop at home to rebuild this summer so that it is ready for the truck this winter!
