Hello everyone.

The cylinders of our roadster engine was oversized bored five times. Is it realistic if I estimate the mileage at 5 X 60,000 miles = 300,000 ml / 500,000 km?

Nahh. That would be over 300,000 miles. An engine that was operated on dirty/dusty roads will require more frequent rebuild than one that is operated in cleaner environments.

Also, how do you know the engine bored 5 time? Maybe the engine had a wrist pin score a wall that required the bore to be 0.060" or more to remove the wrist pin scoring damage.

I remember in the 70's a vehicle with 100,000 miles would be completely worn out in our area. The roads were rough with more curves, more potholes and really tested vehicles. 100,000 today isn't that hard on one. It's still possible I guess for an A to have that many miles but I would think many rebuilds.

For all of my Model As, I add 100,000 miles to what ever the odometer reads if it is between about zero and 50,000 miles. Anything over that and I don't even bother guessing. Who knows how many times it has been rebuilt? who knows whether the odometer is original to that car? Who knows how well it was driven and how well maintained? The list goes on. In addition, people didn't drive as many miles back in those days so 60,000 miles represented many year's worth of driving. By the time the engine was worn out, the car well and truly superseded and usually replaced, then if it survived at all, it sat unused for years. Most were destroyed.
I doubt many of these cars have ever done more than about 150,000 miles.
Just my humble opinion.

When my truck was bored when being rebuilt they had to bore another .030 due to the condition of the cylinder (very worn at the bottom of the stroke compared to worn at the top of the stroke. Unless you know it's complete history, would be difficult to make assumptions.

My 1929 Tudor I bought from the original owner in 1968. The owner lived on an island and the A only had 52,000 original miles on it. In the last 52 years I have added another 52,000 mile to its count. Now showing 104,000 miles on a working odometer. The car is still tight and runs like a new car. I did do a frame off restoration in 1971 because it needed new wood. So some of the low mileages that you see on the A Fords could still be on their first time around.

When I was in high school in the early 70's a buddy and I must have taken apart more than 20 49-53 flathead V-8's looking for a couple blocks that weren't cracked between the valve seats.

It was not uncommon to find nearly .040 ridge at the top of the cylinder with stock diameter pistons.
