Lalo,
In the post that seems to have disappeared I just touched on a few thing 'll try and repeat.
Why don't you go to your local library and look up the History of Henry Ford and His Cars... or any other make you might like. I think you will find something on specifications and dimensions and you probably will find it interesting reading.
The hi-boys basically were cars without fenders. Some had a higher stance (sat higher). But, to my knowledge, there was never a model made that was called the hi-boy from the factory.

One thing I did suggest was that you buy a car you like and then get dirty...tear if apart (within reason) to see what makes it work. You might even decide to make moderate updates to the suspension (shocks, springs etc), tear the engine down and have the head(s) milled, put some pipes on the car and so on, etc.

There is a lot to be gained in reading up on a project but nothing beats actually having the car in your driveway and fixing it up to what you want the car to be. Remember, the first car you buy is merely a stepping stone to a more desirable model later on.

What kind of cars are available @ a reasonable price that you show some intereest in?

Talk with you later,

Harris
