stock 216 in the '46 1/2 ton, and stock 235 in the 2 ton.. haven't given me any problems untill recently, when the 1/2 ton didn't wanna start for a bit.. but that's probably all my fault, anyway.
Fired right up today every time I hit the stomp start, and purred like a kitten.
Still seriously considering going with a newer rear and an "open" drive line.. but so long as she keeps running nice, i'll keep it.
If I ever do have to replace the engine, i'll go with a later full pressure 235, or maybe a 261.
