There you go don't get so heated about I'm just trying to help get a cheaper solution than twin turbos

Well for one turbos are for low rpm for pulling and having really good low rpm hp. But supercharges are for high rpm in which you want if your racing in which it sounds like it if your getting a long travel. So they do the same thing but for different purposes

You are both over-generalizing. Turbos have been used for both towing and top end, as have superchargers. It's all in how the total system is designed - Eco with twins tows like a diesel, GTR with twins hauls the mail but not much else.
Understanding that either method, turbo or supercharger, can be tailored for any number of uses it comes down to benefits and negatives of each based on how it will be used.
Turbos are much better for this type application because:
1) no parasitic power loss means either more power at the same boost or same power at lower boost - which is much better for managing detonation in an off road, all out environment.
2) turbos (and centris for that matter) have the added benefit of a large FMIC which makes managing heat (limiting detonation potential) easier.
3) turbos can be remote mounted to reduce under hood temperatures - again ability to manage heat/detonation potential.

Unless the cylinders in the block are in bad shape don't bore them, or bore them as little as possible to fit the new forged pistons (that you size accordingly). Boring a block is not a power modification. It's for fixing worn or damaged sleeves. Stroking the engine is where the power increases are made.
When you hear ppl say its bored and stroked, the bored part means squat other than they had to fix or clean up the cylinder walls.

So F1, NASCAR, V8 supercars, all those engine builders are wrong? And you sir, you know more than them? Highly probable.
High horsepower high RPM engines run large bores and small strokes. Keeps the piston speed down, over 72 ft. per second and things start to get all bendy inside. Not a good thing. So hence the large 3-4 inch or so bore of V8 supercars and the less than 2 inch stroke. So they can sing at 7-9k RPM all day and never wear out. If the OP never wants to see some screamin RPM I wouldn't do a thing to the block.
OH, and or the turbo vs. supercharger debate? Lets not forget heat soak with the super's. Go turbo.

even for places to go out legally and safely and open up the truck is unknown to me, might take a few trips out to oregon dunes as they are not too far
as for long run durability, do you think the raptor kits are capable? I am a mudder by trade, and beleive the gas will get you out of more places than the brake so tend to be a tad bit hard on things. the suspension is the one place I am definetly willing to spend every penny I can as this truck will see some public road driving.

I don't know half as much about engine technology as you or the other person you are at a flame war with, but why would anyone recommend keeping the stock displacement instead of boring it out to 6.0L - 6.2L if you plan to use a supercharger? Could you not increase the displacement and run more boost to bring more power or am I missing something? Not trying to sound like a dumb ***, just a realistic question.
I think it was Hot Rod magazine that did a comparo with a 8.5:1 350 at 22 psi and it made 575 hp. Then they had a 10.5:1 350 at 12 psi and made 625. IIRC.... Of course, its all in the tune.
