Thoughts on this Dodge D50 pickup with a smallblock

Little trucks are fun, I just gave a V-8 Dakota to my nephew. He just turned 16.
Kids have alot of energy, the first day he put a battery in it, dumped some gas in the tank and it fired up and idled.
He fixed the brakes, with his dad's help.
A week or so later I went up to their house, there was a set of black marks about 100 ft long by their house.
I hope he does not hurt himself in his first vehicle.
