    De-Carboning a V8

    Is is safe to use SeaFoam on a V8 the same way I would on an OB?<br /><br />When I had an OB i would put one can of SeaFoam in a small gas tank and add enough gas to equal one gallon, then run it through the engine a high idle. I was just wondering if this would hurt a 5.7L
