Default Stock pistons and rods last to what HP?

If Im upgrading my engine and making 500-600hp, when should I upgrade to stronger internals? Although Im probably going with a standard wet efi system for my 5.0, Im considering running a direct port and running a large shot of Nitrous, like 300 with a zex kit, 400 with a nitrous direct, or another number around there. If i go this route I am totally up to all the work required, down to rebuilding my rotating assembly.

I was also thinking if I needed new forged Pistons and connecting rods, that I might as well go big, like 331 big. But overall im just looking to see if I what I would need if I was making 600 hp.

For that HP you will need at least rod bolts. Not sure what year you have, you may already have forged pistons.

I have a 95 GT. Looking to do anything that I need to to make it work. If im replacing the alot, I might just go with 331. Just trying to see my options.

you will need at least pistons and rod bolts, I would not trust the rods to that power.

And if your going to be pushing 600hp, I would look into stiffining your bottom end. That 2 bolt main wont last long.

What mods do you have now? Telling you know its going to take alot of $$$ and work to get it to push 600.

Right now I have minimal done to the engine, Flowmaster exhaust from front to back, Pro flo intake, lumpy cam, strut tower brace full subframe connectors, short throw shifter is it.

I want to be able to take my car to the track and still drive it daily as my ride everywhere. So i had an answer with a large shot of nitrous. For me a large shot fo nitrous is the answer, i can run around with my naturally aspirated engine power and have some gas mileage, then when I run at the track turn on the nos and have good times. I was looking into kits and there were for 150-300, 200-400, or 200-600. Naturally I want the 600 but that is HIGHLY unreasonable, Im putting it out of the equation. I havent dynoed yet but im guessing around 250 or so hp, and with a 400 shot it would make it about 600 or so, and a 300 around 500. Id be willing to tear my whole engine down to peices with a direct port injection this winter, I just need to know what I need to do.

I thought the stock block was only good for 500 hp?

Good point, he will need an aftermarket block if he wants to last very long.

Driveline Anybody? Have you thought about that yet? Youll need a new clutch, U joints, driveshaft, axles, and some high quality gears to handle that sort of power no?

Clutch and Ujoints are actually fine, forgot to add that but there is a high performance clutch and a lightweight flywheel connecting me to the ground. 8.8 Axle is coming soon regardless, and the driveshaft i didnt think of. If the stock block is only good to 500 hp, then probably abort the plan, I cant afford a new block, or i could go with a lesser shot.

Thanks for the heads up.
