I would hope it has a forged crank with the supercharger.
Just trying to get a handle on the basics of this 4.2 engine platform.
I was told it was no way close to a Ford engine in a previous post.

There does not seem to be many folks that have dug into the internals. I guess I am just use to the Chevy group and the extensive amount of info available. Of course not a lot of folks buy a $70000 car and tear into it so I guess it is understandable.
I am hoping to learn more here, so sorry if I ask some redundant questions that may already have been answered.
