Actually I was looking for measurement from the flat part of the floor board to the top/level part of the 3 speed transmission. Sorry I wasn't more specific. The depth from the back of the engine to where the transmission flattens off is approximately the same. Where the Powerglide flattens off is inch higher then the 3 speed. Hence why I am hoping someone has a truck in a position for a easy measurement. I hope there is more than an inch.
I already trial-mounted the engine with Powerglide on the frame. The Powerglide is 1/2" longer than a 3 speed but will still work with the pickup drive shaft, but it will be a tight fit. It just mean the u-joint yoke will be slide further down onto the drive shaft.
