There's a really good book on Stovebolt 6s that is mainly concerned with adding performance. Can't remember the author's name, but he was Spanglish.
The 194/230/250/292 was designed after GM became capable of thin wall castings. These engines weighed maybe 75% of what the 216/235/261s weighed, and were about two inches shorter in height, except for the 292, which was the same height as the 235.
The 230 was mainly a passenger car engine, and was used in quite a few. The first new car my parents bought was a 1964 Chevelle station wagon with a 230 in it. Lots of torque, and it would run a 80 mph all day in front of a Power Glide.
The 194, and the 2.5 liter 4, were for cars like the Nova. The 250 was often used in place of the 283/327 in Canadian sedans because of the tax formula there. The 250 was out for a few years before the 292 came out. In one way, GM really screwed up the 292 by moving the passenger's side motor mount. Seems to me like they did it because of some conflict with the placement of the oil filter boss. (???) The good thing was that the block was tall enough so that the driver's side front head bolt did not have to pass through the water passage.
Please correct me if I am wrong.
