IND265 engine parts

[Fargo51]

I have a 1951 Dodge Fargo FO-1

The engine has been changed to a  IND265 (25 inch head)

I am in need of a new or used camshaft that will fit this

Mine is broken into pieces

as well as other parts like pistons and maybe a connecting rod

or am I better to try and find a donor  engine

I am in Ontario Canada

any help would be appreciated

Thanks
