OK - here's a new Slant 6 article in Hot Rod (checked the date this time - Aug 2017 ;-))

funny how they missed the 198 slant and claim only the 170 & 225 were made.
Not true, they stated Chrysler made the Slanty in "mostly" the 170 & 225, I guess figuring the three year relatively unpopular run for the 198 wasn't worth the
mention. I'm sure they're relatively unaware of the popular options the engine provides for modding, either the long rods for the 225, or using the crank to
stroke the 170. & for the purpose of this article I guess there's no real value in including it, but You'd think just to be thorough....................:rolleyes:
