Contrary to common opinion, if the car is rebuilt to Factory specs you can expect a car capable of sustaned 60 MPH.
The car should be comfortable to run 50-55 MPH all day long. You are not hurting anything if the crank and rods were built to factory specs.
Yes, it will stop fine for something with the thin tires. The braking limits are the rubber on the road.

Quite often you will here tell of 40 to 45 MPH. Every car someone tells me is only good for those speeds I look at the mechanical condition of the car and doubt it is safe that fast. I guess I am picky.
