When did they? im used to all Sherman’s having a top Speed of 30 mph but today i seen all but the M4A2 (76) W (US) cant go 30 mph anymore while the rest range from 21 mph 23 and 25. if im correct shermans used a Spicer manual synchromesh transmission so why would they be completely different speeds. But the M4A7 (76) W used a GM 6046 while most others use the Ford GAA V8 but idk about the 76 W Jumbo it has 456 Hp. if anyone can provide more info about them im all ears im not good with looking up Docs but i try.
they all had basically the exact same speeds output to the sprocket. maybe youre getting mistaken for their performance in arcade battles
