I've got a '86.5 Nissan Hardbody 4x4 that was my first vehicle. The z24-gasser is getting ready to be pulled for the 3rd or 4th time, and I'm considering a Detroit Diesel swap.

Does anyone know the dimensions of these engines? My main concern is fitment in the engine bay. I know that a 26"x26"x26" 4-cylinder will fit in there with no problems. I'm not sure what the dimensions of the DD's are though.

It can't go over 65mph at the moment, so I'm not too concerned with power. I'd just like the ability to have an engine in there that will run forever, and occasionally partially run on its own used engine oil. And it will sound much better.
