M7B1 Priest came later in production then the M7 and was based on the M4A3 Sherman.

It was produced from March 1944 until February 1945 by the Pressed Steal Car Company. Total No. built was 826. Major improvement was the implementation of the GAA V8 engine which was without any doubt the best tank engine built in the US during WW-II.

This engine supplied its power via a double clutch plate system and propeller shaft to the front mounted transmission pack. The transmission used was the synchromesh type. It had 5 gears forward and 1 reverse. The synchromesh were actual unnecessarily for the Ford GAA V8 because by this type of engine you already can shift gears at 300 RPM. 
The synchromesh type gearbox was however an absolute must for the also widely used radial-engine Continental radial-engines R975-C1 and C4, which was basically a 9-cylinder air-cooled airplane engine with an output of 450 bhp which was very difficult to drive. That is why the synchromesh transmission was standardized.

The Priest M7B1 saw first action in the battle of the Bulge. There the M7B1 proved to be very effective. Same for the campaign up to Berlin. In the ‘50s, when the M7B1 was widely used in the Korean war, the elevation of the gun was inadequate to be used in the mountain area. To improve this many Priest have been modified in this period by raising the howitzer and add an extra segment in the pulpit. This modification was standardized as the M7B2.
