For reference, here’s a table showing E-Series chassis availability for E-350 and E-450 by wheelbase and weight ratings (GVWR) — since it keeps coming up in different threads.
This is 2021 ModelYear, but hasn’t changed much. Previously it was 6.8L V10 or 6.2L V8 in lieu of Premium or Economy 7.3L V8 engine choices, respectively.
