Welcome to the forums.With that fresh of a motor and chassis...there shouldnt be much wrong with it, Keep it maintained and it should keep going good. you may want to go over the 5 speed install the previous owner did just to make sure nothing was done poorly. Even simple stuff like the design of the crossmember and shift linkage add to how well the car drives.As far as all the other stuff, try searching for common matinence issues and things to look out for.
Just curious, did he buy the car from a member here?
I hope your dad has good luck with the car
