I've been debating the Darton sleeves in the '03 we have and tentatively have decided not to open the engine till we decide to screw power adders to it (boost in some form for us).
The 4200 has so much more power stock (than the 228) we figured it would be a good idea to try it that way for a couple reasons (time and $$$).
We plan to "knock the dents out" of the truck and drve it patina'ed (legit patian) for a bit, but that's us, we can't seem to resist the urge to tinker, and that gets real expensive when you have to repaint parts of whatever it is each time you change something.
Eventually it will be shiney though.
