I would just find a block and take it to a machine shop. No matter what it will have to be bored or honed out to whatever pistons you use.

either that or what would i have to do to the block of my engine in order for it to be the equivalent or buying a reman? see what my plans for it are....i wanna put a bigger and better crank in it, bore and stroke the heads along with port and polish, pistons, rings etc. 99-04 upper and lower split port air intake manifolds, u/d pulley set, and eventually maybe supercharge? i also wanna do other stuff to the drive train and what not but right now my main focus is on the engine itself. any suggestions?

You could buy a 3.8/4.2 at the wrecking yard & build it over time, in your garage, acquiring the parts as finances allow.
When it's finished, do the engine swap in a weekend, then sell your old running engine to offset the costs.

I was unaware you can get the heads bored and stroked out :p

If I were going to build a performance engine, and didn't intend to race the car, I would do what Chris is doing. He's starting with a 99+ engine, which has the split port intake, and installing new forged internals and having the top end ported out. I would stick with a 3.8L crank but you can use a 4.2L if you want. Then just leave it normally aspirated. If later you want more power you could add intake boost.

This may jsu tbe my thinking, but if yur gonna have the engine out and work everything else up....you might as well stroke it to 4.2/4.3

I guess I don't know how much benefit there is to going from 3.8L to 4.2L.

I thought it was a relatively small change compared to porting the top end. Certainly if you plan to increase the power you should go with forged internals.
Adding a turbocharger gets more fuel/air in anyway.

Perhaps someone knows what the gains are supposed to be from various modifications.
