Nusbaum Farms LLC Bellfountain, OR | ...Same bore & stroke as the 3406. I think they were one of the more successful V8 diesels of the 70's, which I suppose might not be saying much.
A contractor neighbor has one in a '78 Kenworth W900, bought new. I have no idea how many miles it has, but as far as I know it's never had any major issues. Dual straights sounds pretty cool....definately a distinctive sounding rig.
