B vs RB

RC Moser said

68 thru 73? HP 383s were all RB due to the 3. 375 stroke. That's way I understand it. If it's got 3.375 stroke in 383 it was RB?

To quote allpar in the article I posted...
"The 383 cubic inch RB engine was only available in 1959-1960 on the US built Chrysler Windsor and Saratoga"

So it's rare you will ever even see a 383 rb and for sure dead by 1960

Little known fact a "chrysler 350" exists also in the B deck lol
