Look what followed me home....
A little update....made the decision to pull the heads and send them to Kris Starnes, who does the porting for Al Papitto and a bunch of other shops.
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.

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.

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.
