What piston in a bronze cylinder?

Rich,

Here is a list I picked up from somewhere showing the compatibility of materials with each other.

A little looking and you should be able to find which materials are good together

As you are not having a counterbalanced crank I would go for aluminium, the lighter recipricating weight will make for a smoother running engine, quite common on model traction engines. With CI piston rings.

Cast iron runs very well on cast iron.

Well unless you can make a hollow cast iron one like most full size would have had
