I will have to ditto G.M's comments with a few supplements..
My '36 had a Columbia under it when I purchased the car in 1952, the car was dead stock w/21 stud engine and a 3.78 rear end. The engine was a Meyer's/Welsh Ford engine which probably had been over-bored.
Having driven farm trucks with two speed rear ends I had no difficulty adapting to the proper way to shift a two speed rear end.
I drove the '36 almost 40.k over a two year period before I pulled the '36 engine, replacing it with a well built 59 AB. The added power of the built 59 AB engine did improve the power and performance of the Ford.
In 1955 I replaced the original Columbia with a '46-48 Columbia. The application was done using the stock '36 drive-line and center section. I used a complete '46-48 Columbia with '46-48 axles and housings and '37 radius bars. All of the controls are the '46-48 electric over vacuum, which I placed on the fender splash pan in lieu of on the left head.
The whole conversion has been running for over 50k with no problems...
