Chrysler 300’s never had the golden lion label on the engines, or in the brochure. That golden lion was for the “regular” cars. 1959 300E had these decals on the valve cover.
The 1959 300 E brochure calls it a “robust 413“. The 1960 300 F brochure uses two catch phrases, “From this 413 comes instant power”, and also “413 cubic inches of slingshot performance“
And the hemi that was in a 55-58 Chrysler 300 is not still in production today. Been through several major changes.
