Default Hyper vs Forged piston for 6.0 build

I'm starting a gen 3 6.0 build , it should be around 500 flywheel hp with cam, heads, tune,etc.. Car will be weekend warrior and plan to do some occasional street racing against the newer cars when opportunity arises, with tire burning etc... Will hyper pistons be enough? Or would I need forged?

If staying naturally aspirated at 500 flywheel hyper pistons will be fine.

As said a hyper is fine for that power.....but if you're building it anyways why not go forged for not much more $ and give yourself more head room for the future. I wish I had.

Exactly, why even rebuild it if your just going back stock? The stock stuff will handle 500Hp with ease like G atsma mentioned

Find some factory flattop pistons and run with it. I wouldn't bother with a forged piston unless you're changing the entire rotating assembly.

Gotcha, might be cheaper to just get one that doesnt need to be rebuilt, but if money isnt an issue then have at it.
What happened to the engine that is requiring it to need a full rebuild?

Also if your having it bored and staying N/A you might consider having it bored to 4.065 and running a set of LS3 pistons

I like this idea. If staying NA and you can get an entire LS3 rotating assembly that would be ideal. Already balanced with stronger rods and more cubic inches.

I have a feeling that a used ls3 may cost the same as building a forged motor yourself from scratch.

He was just referring to the rotating assembly, not the whole engine.
But unless his engine had bearing failure then his crank would be fine, and if he has Gen 4 rods all he would need is pistons/rings from a LS3

It's a gen 3 6.0 engine that I could get for like $400, but it's been sitting outside and got water in it which I freed it up, not that bad inside (3 cylinders kinda rough on top from freeing it loose, but bottom is black like they never changed the oil... rather build it back than chance it.

I would buy a used 6.0 but I can't find one I can witness running , plus they like 1500-2000 here and that's with high miles. Anyone have a source for a decent running 6.0 engine with no problems?

High mileage isn’t usually an issue, especially since the main wear items usually get replaced like lifters, pushrods, valve springs. there are some one eBay from reputable sellers for $1200-1400 shipped.
