Oh my gosh man...your spelling is atrocious. You mean to ask will the 4l60e RELIABLY handle 510rwhp/460rwtq?
And brake is the pedal in your car you use to slow down and stop. Break means to damage something or destroy it.
Now to answer your question. The 4l60e, from what I have heard, will not handle anything beyond 400WHP safely. Beyond that and you're asking to BREAK something.

A top-of-the-line well built 4L60E will handle that for a reasonable amount of time. Such a unit will cost $3500+ and still have a weak 3/4 clutch. Adding the new Sonnax extended-depth input drum and billet input shaft may solve the 3/4 clutch problem, but add another $1000 to the price. Even a $4500 unit will probably eventually break. At that price and those power levels, you should consider a 4L80E as $3500 will get you an excellent unit and that would leave $1000 for conversion costs.
Just my opinion.

I searched and found PATC company have the re-built kit of almost around 1000$ with shipping\handling and installation is around 800$, while i managed to find a used 2010 4L80e for almost 1300$. Will the 4L80e in stock form will handel this power without any upgrade?

Yes but you will have to make sure you have everything for the conversion, and expect to lose some more hp through the drivetrain. I personally like the stage 2 4l60 from performabuilt. Rated at 700hp, 1yr warranty, and under $2k brand new.

the 80e should be able to do it but might as well upgrade while its out. have you looked at the additional costs that are involved in swapping in an 80e such as cross member, custom converter, flexplate, and the wiring that is involved? for what itll cost, you can have a kick *** 60e for the same or even less.

I ran a stock 80e and converter, then with a aftermarket converter, for about 12k miles and 3 years. This was with minimum power of 550whp/500wtq up to around 850whp/700tq
Turbo 6.0L in a 3900# car and 3.08 gears in the back. never had any problems and it didnt slip, ran 130's mph up into the 140's mph in the quarter

The question is will you be happy forever with 510hp or will you be tempted with Nitrous, Supercharging or TurboCharging?
If you look at and compare the internals of a 4L60E with a 4L80E, it is an OMG moment, "I want a 4L80E".

If you are going through a ton of work already and have the budget plus plan to run sticky tires at the track then go for the 4l80. If it's a street car then a well built 4l60 will hold up.

The engine is currently N/A of 418ci. Later it will have a wide wheels rims to get 315 wide tires semi slicks. Also after two years it will have twin turbo plan to get around 800rwtq. I will give RPM & FLT a call...

LS6,
One of our Level 5 4L60e transmissions will handle your power goals for a very long time. We have customers who have literally thousands of passes logged on their RPM Level 5 4L60e transmissions.
The most important thing to keep in mind is when dealing with performance automatic transmissions is the parts inside aren't quite as important as the person who assembles the transmission. It is just like an engine. You can put the most expensive parts in the world inside of it. If the person building it doesn't know what they are doing it will fail every time.
Our Level 7 4L60e transmissions have been tested to 1000hp in a 4000lb car running 8.90s in the 1/4 mile. At 1000hp we ran over 100 passes on it without failure.
If you have any questions please let me know.

I agree with Jeremy that the 4L60E, when built properly, will be OK at that power level.
It's no secret I'm a big fan of the 4L80E and that's why I've made it our specialty. 510 RWHP is getting borderline but is still within the realm of a what a 4L60E can reasonably do.
The conversion costs for a savvy DIY'er are not terribly expensive. Transmission and converter, crossmember ($175-250), wiring ($200 or less), tuning (may already be in play so no real additional cost or will likely be necessary in any case), yoke ($100), cooler line mods or replacement ($20-up).
The 4L80E is a pretty simple swap in a 4th Gen F Body and many other cars/trucks.
We also do 4L60E's. I have some at the 600+ HP level that have been out there for years now doing pretty well.
