Turbos are not simple, lots of plumbing of intake and exhaust, any free space under the hood is gone, lots of heat under the hood, got to have the right blow off valves, ignition timing becomes a lot more critical... lots more complicated.
As for the weight differance in BB and SB I was stateing the weight differance I personally measured between a 67 440/727 and a 71 340/904 (I know a 340 never came with a 904 but the one from a 318 bolts right up  ) both still had the iron intakes iron heads... and the differance between the two was almost exactly #200 a low deck might be a little closer but I did not have one to weigh.
Disagree. 200lbs is a ton, there's alot of cost involved in swapping to a big block, and you don't need an aftermarket crank to make 650 boosted horsepower. Bottom line as stated by others is a 3600 plus driver car will need 650 horse or better (with 3.55's to boot) to go 10.50, it takes a pretty serious stroked SB to make that power, call Ryan and price out a 'budget' 700hp SB, and a 375 horse smallblock with boost will do the same thing with ease, and be tons more streetable.
There are many ways to skin a cat, blow off valves and turbos are very simple once you learn the basics, especially if you have any fab abilities at all.
11.48 @ 120 with a 1.80 60' 318, stock 1.88 heads, stock 904, Pump Gas, 13 lbs of boost.
9.94 @ 134, 318 on pump gas, 14 lbs w/ Eddies, transbrake 727, 3600 lbs, 3.54 gear and 28's.
