Is there anything that makes the Model T engine inherently inefficient, unreliable, etc? What's their rated horsepower? RPM range? Are they relatively heavy? What would you expect to pay for a complete engine that needs an overhaul? Recently overhauled? What did Model Ts have for a clutch and transmission? How does the timing control work? Can that be replaced with a regular distributor? Is the Model A engine much different in these regards? Do T engines sound similar to As? Electric starter?
