Building a good blower engine isn't quick or easy, but it can be done with enough determination, money and a plan to follow. Given your USN engine room experience, you should be able to do it.
Watch the S/C thread..... I'm real close to building a new engine..... should be starting it within a week..... as soon as the block and rotating parts come back from the machine shop. The crankshaft is balanced - I'm now waiting for the block to be decked, align honed and bored.

I like the words of encouragement, i'm planning on a procharger, over a blower. my question is what kind of psi can i run, and is there oversized pistons so i could do a bore? and i guess 1 more question for now, what kind of power can the automatic tranny take? ........................and FYI these little engines arnt like the blown detroit 12v71's thats i made scream!

A ProCharger IS a blower - it just doesn't make much power under the curve...... it's more like a turbo.
Quote:

It depends entirely on how you build the engine.... what pistons, what crankshaft and how you fuel it and if/how you cool the intake charge. Some 3.0L engines are running waaaay more boost than I would ever try. 6-8 psi will make a very noticeable difference.
Quote:
is there oversized pistons so i could do a bore?
For cast pistons, up to 1mm (.040"), but you're boost limited on those. For forged, .5mm (.020" over) can be easily found.... larger if you want a complete custom design.
Quote:

Plenty.

I've made a few Detroit 6-71/8-71/12-71/6V92/8V92Ts scream also..... I kinda like driving fast fishin' boats...... 
Someday, I'd like to stab the throttles on a pair of these in a lightweight boat:

alright heres a crazy idea, my project engine dosent have an intake manifold . and ive found lots of ford lighting s/c and pontiac 3.8l blowers could these work, but how do u control the psi and make it fit a manifold . i'm inspiring (sorry lots of questions )

The Ford Lightning and 3.8L blowers ain't ProChargers - they're Eaton Roots blowers.
You control the psi via pulley size.
To make it fit a manifold, you build your own manifold to fit the engine and blower:

Since you said this engine is out of a "2000 Montero" and also a 3.0. You need to verify. In 2000, all monteros came with the 6G74 3.5 24V SOHC. If its a 3.0 (6G72) and of 2000 vintage then it perhaps came out of a Montero Sport.
Either way you need to factor in that both of these engines have no distributor and have a different ignition system that utilizes coil packs. I know your saying you want to run MSquirt but with out the baseline of a wiring harness and ECU from the donor it could be quite difficult to figure out.
If it were me I'd supercharge the SOHC that you have in there already and mybe find a complete donor with harness. Not saying it cant be done, but just saying..

Frank, if i can get this engine together do you think it would be worth the money ,effort, and headaches to swap it into my 89swb?

As Justice said, you'll have to use the heads with a distributor unless you're prepared to go the MegaSquirt route - or change ECUs and wiring harnesses. I'm not sure that's worth it unless you're going to build a blower engine.
You need to decide what you want to put in the truck and build it from there.

well i got the engine for 40bucks, so if i cant use it, i am sure someone here can. i really want to supercharge my little truck. i noticed you had alot of wires in your engine bay. i really want to keep that to a min. i dont want to come off crazy or misguided, i'm just feverishly brain storming. and i'm loven all your feedback.........
thank you
