FI - how big should I go on the short block for a daily driver

I am not opposed to overbuilding if it buys me something for the future. Figure when this truck is done I'll have to part it out anyways. Won't suck to be "stuck" with an LSx block later in life.
It gets compounded every time I cost it out. Have to yank it for a week+ to do the rods for which I rent a car. Add to that a Forged SB can be shipped to me for $6.5k - (the price of my block used + at least the price of rods & bearings) and the overall cost for a beefy LSx isn't so bad.
Maybe I'm nuts....I'm definitely usually overboard.
New shortblock lets me pick my CI as well. Not really a lot of price difference between 376 and 454. Which perhaps is a better question. With my goals (including being streetable in the winter) what combo would you use for Forced Induction and cubic inches?

No killjoy there.
By price I meant for the shortblock. Assuming I then turned the boost down so the power was the same wouldn't the net effect also be the same?
Of course, reality sets in...I don't turn down the boost, have more power, and break more stuff. That is probably a given, but I think in that regard this whole project will definitely get out of hand real quick. Sort of my personality.

6k may be light, lol. Perhaps I wasn't aggressive enough in my goals. In particular after reading Foose04's build log. My previous rig stock did 12.9 so I need this to be faster. I do get bored, but want whatever I build to be reliable. Would have said 10's or 11's, but then we'd be off focusing on the transmission and everything else I'll break. That discussion is for later. 
Now a street tune well into the 12's with potential to kick things up a notch.
Am I correct in thinking the laziness of the turbo will help make the transmission and other rolling gear survive better? Same with the 8-12 no? Oh, and btw in stock form I rarely get more than 12.5.

Quotes since it'll obviously get lined up and run down the track, but really just for a baseline and to see how it is not as an actual track toy.

For the weight of that thing I would use a whipple for the power adder... Good reliable tq 24/7... Not that a turbo won't do that for you but for your goals a whipple will do just fine. I would put it on a 408 or 427 stroker motor.

I vote LQ9 block forged 402 with worked LSA heads, 9.5 compression, and a tvs2300. Solid 750rwhp setup and very DD friendly.
Ive had both, and turbos are not near as fun for a DD and require 10 times the maintenance as a blower. If you want to go turbo later, sell the blower, change the cam, and off you go!
