From "Death Traps"by B. Cooper.

"The M4's engine was supposed to be pulled after a 100 hours of operation."

If you have the luxury of a great maintenance group like the Ami's had, that's great.

"The Ford Motor co.,under the direction of the ordinance dept.,took the Brit Rolls Royce Merlin engine and cut it down to 8 cylinders" This was the new M4A1.
A Brit engine, just like the Mustang's.
The Brits put the 17pder in the Sherman to give it some heavy fire-power.

The Sherman was a good tank for the Pacific theater but I thought the ETO was the priority. It was a poor choice.
