Thinking of getting a Model T

[stickshift]

My first time posting on the Model T forum. I have a "31 Model AA truck but I am curious about the Model T. I have been studying up on the Model T the last few months and I know about the planetary trans and three pedal shifting. I also know the engine is smaller than a Model A and puts out 20 horsepower. The thing I am worried about is the longevity of the engine and transmission. I hear the engine is only good for about 10 to 20 thousand miles. Do they have a shell bearing kit to transfer away from poured Babbitt? This might make rebuilds easier. I also know the Model T was not made to drive at today's speeds and only safe under 40 MPH. Rear brake addition and two speed rear-end a good addition. Anything else I should know that would make me decide yes or no? Thanks for the input.
