<FONT size=2>How much horsepower can stock internals handle on the 4.6 Mustang? Just curious.</FONT>

USAMuscle

I believe in the neighborhood of 400-425 HP. If you plan on using forced induction, it's a good idea to install forged internals anyway, because the rods and pistons in the 4.6 are very weak.
