My 1967 Charger big block has a very unique problem. Appoximately 10k after rebuild there is iron grit in the radiator. When I insert a small telescoping magnet into the top of the radiator it comes out with small amount of iron grit that resembles coffee grounds. I flushed the radiator the best I could and refilled with anifreeze. However the problem continues. Any ideas where it's coming from and is it fatal?
