Best tank engines of WWII

[marathag]

When I was a kid I built the Tamiya M4 and M10 kits - and I switched the M4 turret to the M10 hull. I did not know at the time that the armour on the M10 was significantly less than the M4, but even then the height difference made sense to me. However, would the turret basket in the M4 have cleared the drive shaft in the M10?

Slightly different way of looking at it

M36B1

M4A3 hull with M36 90mm Turret, The M36B2 used the M10 Hull, that many don't realize were all GMC twin diesel powered.
Many of the actual M36 were converted from the Gasoline powered M10A1.

The M10A1 never left CONUS, used for training and then conversion to 90mm TDs and M35? Artillery Tractors.

The main difficulty of using an M4 75mm or T23 style 76mm turret, was that M10 hull had no provision for electric or hydraulic drive to rotate the turret.
