I'm gonna put out an initial guess of 300/350 to the wheels. Peak power isn't the real story though... My truck currently makes 210 ft-lbs at 5400 rpm, the 3v straight up with same mods makes about ~260, and I'm hoping with the heads ported it should be around ~290 ft-lbs at 5400. I'll also shift the 3v at 5800-6000 instead of 5400 now.

Sounds great. I'm not sure about the high rpm shifts, maybe a built converter?

Mercury Marauder stock torque converter. They pull well over 6k with no problems, handle blowers on those cars with no problem, and should stall around 800-1000 higher than what I've got now.

They do make a Stroker kit for it, takes it up to a 6.2 or so. However if your bore it out (.30 over?) you should see a good increase in displacement (~362 aka 5.9L). If you stick N/A some cams and upped compression along with some bore should get you some very nice gains.

Of course you'll need a good bottom end and a tranny that can handle it. Oh and my truck if I leave it in first and hit the rev limiter bounces off about 56-5800.

Who said anything about rebuilding the shortblock? It has 27k, thats why I bought it... The 5.4 already has insanely high piston speeds if you build it for performance and want to spin any kind of rpm, stroking it further is about the last thing I would do for a high hp build. The 5.4 is so oversquare as it is that it struggles mightily to breath as rpm increases because of the small bore and valve sizes. That $2700 crank from Paschal Performance strikes me as something the market simply doesn't need, I haven't heard of a single build using it.... Might make a nice tow motor, but if you need to tow so much that you're willing to sink 4-5 grand in a shortblock then you'd be much better off just buying a diesel.

Now then, if money is absolutely no object you'd pick up a Ford GT block that you could sleeve to 3.700 and install the Paschal 4.415 crank and you'd have a 380 cubic inch modular.....and by the time you topped it with fully worked 3 or 4 valve heads you'd have more into it than my truck is worth.....

On the shift points I'll change the shift points and rev limit to whatever I need in the XCal2.
