| RE: 390 crank removal |

Charlie,
The reason I believe I need to balance the crank is because I opened the engine and found a nickel sized piece of mallory metal in the pan. Upon further inspection, it looks like the piece came out of the rear counterweight in the crank. Inside the hole is some weld bead. It does not have a smooth point at the bottom of the hole like the others do. My theory is that the hole was over drilled and then filled with weld and mallory metal. When the plug came out, the crank became unbalanced and the engine started to knock.
The engine is in a 68 Mustang GT 390 coupe with 4speed transmission.
Thanks
Dale
