I'm planning on building a Diesel stovebolt soon, with an Onan/Cummins inline 6 turbo Diesel that develops 120 HP at 3,600 RPM. It's got the same motor mount setup and bellhousing as a 292, as my engines (5 of them) came out of UPS vans, and they were interchangeable with 292's and Ford 300 6-cylinders. Big Brown would just install whatever engine was handy, but they used the Diesels mostly for highway trucks, and the gas jobs for in-city deliveries. They retrofitted for a different engine when Cummins had problems supplying enough engines. I've done a dyno run on one of them, and they produce exactly the HP they claim.
