Is a forged crankshaft really needed? I am in need of some help on a decision. I have just a bare block now and of course money is always an issue. I plan on going turbo in the future and putting down about 500-650 rwhp. I am going to be getting forged pistons and rods, is it really needed to get a forged crankshaft or anything else forged while I'm at it or can I use a stock crankshaft to save some money? Where are my weak points? Thanks
No...not needed at that power level.
Lots of people making a lot more power than that on a stock crank....

In the LS world and that power level, the machine work is more important than the choice in parts.
You can go past that mark with the stock crank with good machining. If the machining is poor you can really hurt some parts well below that power level.

I've been told that the stock crank can withstand over 1000hp or 1200hp. Can't remember which, but my intention is to hit 700+whp on a stock crank with forged rods/pistons.

Thanks, that should save me a lot of money. Is there anything else that would be recommended to do besides forged pistons, rods, and stronger bolts while I have it down to the block. And what should I have done to the block, I bought it already honed with new cam bearings in it. If I buy a used crank will I be able to just drop it in?

stock crank is fine as everyone here has mentioned
if money is an issue I would look for a complete stock 6.0 motor, do a cam pkg, rod bolts, head gaskets and studs. This will handle 600ish HP with no issues.

also I dont drive around on 20lbs...( thats kill mode ) its usually @ 14lbs since I have 1 bar wg springs
even more ot here, but what is the SLP oil pump good to on my ls2? Im planning on a 370ci setup with oem crank with arp fastners, and a pt88 billet single setup along with quite a few other items. Is this oil pump a christmas ornament with my plans here, or can i still use it for what im doing with this? Im shooting for 850+whp.
