would it be possible or practical to swap a 6.5 turbo diesel in place of the small block in my 1968 C-60? I've heard that the 6.5 isn't a great motor, but I don't really work the truck, and my reasoning for maybe using that motor is that, being a GM product, hopefully some of the mounts would be interchangeable, and less fabrication would be necessary. Let me know what you all think, if it's going to be a lot of work I'd rather get a better motor and make the fabrications count.
