Tried to find some history on this generation of sixes 194/230/250/292 but not a lot online.

Found years of 230/250/292 from "History of Chevy Trucks" by Don Bunn and several online engine rebuilding sites:

Last year of 6 cylinder 235 and 261 engine... 1963 K10 and K20 model.

So, used in trucks:

230 6 cylinder ... 1963-66.

250 6 cylinder ... 1967-84.

292 6 cylinder ... 1963-90.

The only other history source I found from search engines was the wickipedia
article on chevy engines.

You may not think much of its accuracy as a source but it mentioned what some of you had already noted. That a big difference between the 235 and this generation of sixes was the development of a common bellhousing pattern between the sixes and the V8's so that engines and transmissions could be interchanged with much less difficulty than before. Less parts to stock and easier assembly would have surely made a lot of sense to the production managers of that day.

If you think some of my years are off, corrections are welcome. A source for the info would be appreciated.

If anyone knows of good sources for history of the development of this later generation of sixes I would certainly be interested.

Thanks for thinking about it.
