Balance - $400
crank prep - $300 - $1000 ($1k would include nitriding, which is a good
idea)
Bearings - $100, plus or minus
Rods - $300 to prep stock rods up to $2500 for Carillo (Carillos were $360
each, last time I checked)
Misc. seals / gaskets - $100 or so.
So, the bottom end is $1100 for basic stuff up to and well over $4k if you
pull out all the stops. It assumes that you're starting with a good crank,
too. If not, toss in another $100 to $300 for a good crank.
Don't forget the dampener - $500 for the part and another $250 - $500 for
fitment.

It's def. a good ballpark. $5k would def. do it.
It's also overkill for a street motor.
$5k plus a supercharger (hint - buy the kit if/when a discount applies,
you'll save a LOT). That's $5k for all the good stuff in the motor. If you
do it right, you can make a lot more than 140 to the wheels, so this is
actually pretty reasonable considering what you are doing / getting.
Regarding the comment about using an alternate power plant, this is
exactly why some folks go that route. They don't see the cost / benefit of
tweaking the stock motor far, far beyond the design specs. But some if us
get our kicks by tweaking the motors... viva la difference!
