I recall.....When the Chevy 2 came out in 1962, the standard engine was a 4 cyl. that was the new 194 cu. 6 shortened to 4 cyl. That base engine was offered for years but did not sell well so they sold it to Evinrude/Johnson. They used it for many years. The hot set up in those days was to find a head from a boat motor (crossflow -more H.P.)When Chevy realized that the Vega had failed, and they had no 4 banger for the wave of small cars coming out, they bought it back and reintroduced it as the "Iron Duke". I think it was bored slightly so they could use pistons off the pontiac V-8 . Then with the development of the "new chevy of the 80's" - the Citation, it was reintroduced with a crossflow head for sideways mounting of the engine in that front wheel drive platform. Those heads do not interchange on earlier blocks since they also changed the head bolt pattern. The motor is a very tough design(chevy -6 basically). TerryJ
