These engines produced 60 and 59 horsepower at the rear wheels respectively. Neither engines have a pressure oil system.
Quite frankly, I don't think that it makes a bit of difference based on my observations. However, I'm a firm advocate of having A engines balanced by a professional machine shop.
The Durango-Silverton Narrow gauge railroad has a facility in town to do babbit pouring. Someday I'm going to ask if they would do a Model A engine.

Denis, what have you done to the engine to get 60HP?
