Just go look in a jegs or summit catalog. You can pick up a nice eagle rotating assembly for 2k or so. You will be fine with that..

Without a blower, your prolly talkin 4k, With machine work, thats putting it togather yourself, with a blower tac another 4 to that at least, new heads, another 2k or so. The first thing is yah need to find out how much you have or want to spend, go from there, again if money isn't a problem just get the stuff, lol

You shouldn't have a problem SC'ing that motor, keep the boost below 6psi, intercooled, run around 11.5:1 @ WOT, run same timing as stock, only use 91-93 octane. Motor has 8:1 compression and we've supercharged many of these in carb'd form. I actually did one on a EFI version, it's gone over 700 hours, non intercooled 7psi. Certainly not what I expected, but the low compression, low water temp, fuel through SC really makes this a save setup.
Increasing the cylinder pressure with 6lbs of boost will not hurt the rods, increased RPM's will be the worst thing you can do. In all our years, rods and crankshafts break far less than 1% of the time on stock applications.
Thanks,
