Mervyn and Barry,
The engine is an NH-220, which is 743 cubic inches, naturally aspirated, with 220 HP. The NHRBS 600 was also 743 cu. in. , but it had a blower and put out 300 HP. The guys that used to drive trucks with that engine said that they were really loud.
I'm not sure who made the transmissions and differentials, yet.
The cab does look like an R-190 cab, but I think the cowl is longer. I hope that they're the same. My cab needs new back corners and I know where there's an R-190 cab on a junk truck that I can probably cut the corners out of.

We're even now, Frank. Some of your projects make me a little envious, too. One in particular...
