Does anyone know if chrysler were using 426 mw blocks for 413 chrysler 300 series for 1963/1963 models?

I'm going to say MW blocks were only used as race engines. MW blocks have bore notches to clear the 1.88" EX valves and that has no business being in a Chrysler. Now, it MAY have been possible a MW block ended up in some not normal application for the sake of manufacturing deadlines but as a rule I'd say no. The logic I'm using is 915 "440" heads have been found on 66 383's.
