Nothing runs like a 283. The only real difference is the pistons themselves. The gaskets and bearings all fit other engines. If you are not in an immediate need, keep an eye on auction sites for a set of pistons. I gave away a set of standard bore stock pistons a few years ago. I'm keeping the lightweight 11.5:1 set I have for a race engine.
The other option is to build a 350 or 400 with your stock intake and valve covers. The top end tin will disguise it as a 283, yet you'll have a bunch more torque, which is useful in a truck.
