More or less you pay for what you get. No need for a forged crankshaft. I'd spend the savings on a nice set of pistons and rods. Definitely go H-Beam rods and some flat top pistons with valve reliefs (more compression and valve clearance). I personally have JE pistons and scat rods for a nitrous motor. Other guys with more experience in short block building may want to chime in.

ok should I keep the stock gm crankshaft or get a new one since the motor has 80K miles on it. Id rather spend a few hundred more and have it reliable

No just have the jorunals polished and you should be set. No need to buy a new crank.
