I bought a blown motor and was wondering if there's anyway i could tell if it was safe to use some of the parts i found. I was told the motor blew due to lack of oil. Upon looking at it more closely in my garage i noticed that one side of the decomp mechanism was broke. The piston moved freely before i took the cylinder off...So it didnt seize up. I bought the motor with out the clutch side components and without the valve cover who seperates those anyway! but whatever. There's a little rust on the cam and springs. I know so far it had a wiseco piston, HR cam and springs, HR con rod. Will a stroker crank have any identifying marks on it?
