2) Magnafluxing rods…did they scrap those that failed, or were they used in 440-4 motors?
Not to get off topic here…
The rods were subjected to a Zyglo inspection which is non destructive but more effective at detecting flaws (google it)
The ones that failed the test were used in police, motor homes and other heavy duty applications well into the mid to late 70's. to my knowledge they all carried the same casting number so it is impossible to tell a true 6 pak rod from a failed but used in HD applications. Please correct me if I am wrong
