[TR] Question for listers

[Michael Ferguson]

Hi, Jim. It is my understanding that it is very difficult to weld cast  
iron, especially in something subjected to the stresses an automobile  
engine must endure. You might do a search on welding cast iron on some  
of the welding forums for more info:

Good luck!
