Flex's post is technically correct. You said forged internals and that is generally taken to mean crank, rods and pistons. If anyone is running a forged 4.2L crank he/she hasn't posted up about or advertised it on the 'net where any one of 1000 people in the 'Bird/Mustang/F150 communities that want one would've seen it.
There have been several that have inquired (to say the least) and a few have gone so far as to check the cost of having one made with a manufacturer - Pete or Talleywacker over at v6p if memory serves - and they bailed because they got astronomical numbers for one off pieces. I don't deny that they can't exist, anything can exist with enough money thrown at it but it would certainly appear that even the highest hp guys running 4.2s are still running stock, cast Ford cranks even if they're suffering from the "bug". Therefore the ability to run "forged internals" in a 4.2 does not yet exist unless you've got a big, no huge, wallet. Therefor it ain't near as simple as
1. Use forged internals.
2. If you don't want to use forged internals, see #1."
