Get a 35 spline locker and be done with it, I know guy that went 8's on his that used to work for lenco.
If you're street driving a high power street car and on street tires it's a different story than running a 30x10.5 slick and having 850 hp and dropping a clutch at 6500 rpm.
What exactly is your intended use for the car?
If you drag race and have that much power I think a locker is the only way to go besides a spool.
I was looking at your sig and my plans are pretty close to the same as yours, 800hp pump gas procharger street car, I am going with a spool in mine.

Itīs going to be used on the streets and itīs with a 4l60e so itīs easy on the rear
Iīm trying to find how much hp the true trac can take,i donīt like the idea to use a locker if i can skip it,i would just put a spool in it on the strip

Why don't you like lockers? How would you just put a spool in it at the track, you're going to have 2 separate 3rd members?
Sounds expensive to me.
You're also talking about running 8's down the road in your sig? Thats a pretty mean 60ft to pull that.
Might want to post this in the gears section so you can get a sponsor there to give you a better opinion, being this is the drag racing section I would say locker or spool, if you want detailed differential info on power ratings, I think the diff/gears section will give you the best responses.

I had a spool in my SS, and it's getting a tru trac put in it as we speak. A guy around here has a tru trac in his 10 sec Cobra that makes a lot more power than I do...I have only heard good things about a tru trac.
If anyone needs a spool, i have the one thats coming out of my SS. Has a few thousand street miles on it. Came out of a Strange 12 bolt with 33 spline axles..

I ran a Tru-Trac in our Moser 12 bolt and it never blinked. We pulled 1.29 60fts and put the car on the bumper with it. We make 538rwhp/500rwtq. The car has ran in the high nines with a 3.90 gear.
This is with a 4L60E also. I was very impressed with the Tru-Trac. I'm not sure if you are using RWHP or FWHP calculations,but I felt like I was pushing the limits of the Tru-Trac.
If you are full weight and pushing 700 rwhp, I'd opt for a spool. It'll handle some street use with a street tire that will give. Traction should not be expected on the street anyway with a 4L60E low 1st gear.

I'd go with a locker. Obviously you plan on driving this a lot as you're sticking with the 4L60E. The only time you'll notice you have a locker is around turns. It'll make a clicking / clacking noise. Other than that, no problemo and it'll hold pretty much anything you throw at it.

I donīt like the idea to park a car with a spool lol
Itīs a lightweight car so if the truetrac can hold up iīll use that but yes,locker is the stongest just want to use the TrueTrac for a DD

I drove my 65 nova on the street and was able to park it no problem, I had 33x16.5 slicks on mine with a spool and 4,500 stall, and with a slightly stretched wheel base of 114.5 it still wasn't hard to park.
Now when it comes to u-turns well those don't go so well with a spool, I had to do 3 point turns when I made a u-turn. 33x16.5 slicks don't slip as good as a street tire wheel when you turn with a spool.
I'll bet you one thing, you won't break a spool with 800hp, now running 800 hp on a true trac and street driving and drag racing also, I'd personally not feel 100% safe going that route.
Here is a photo of mine so you can see I'm not talking BS, I drove this car for a few years on the street and raced it almost every weekend on private roads of course

you do need to remember that driving with a spool and having a soft tire in the rear is alot different than if you have a street tire. A slick, or similar, will absorb most of the 'shock', but a street tire will not. And you will get alot more vibration compared to having a slick, or something with a soft sidewall.

I know iīm strange but i donīt want to build a high Hp DD and have compromise in the rear end and driveability
Yes i would drive it on low profiles so the Spool is not fun at the local supermarket lol

You're at a point where I wouldn't recommend a Truetrac, and I don't like the way a locker causes the back of the car to wiggle around either. If it were me I would go with a spool. It is cheaper, weighs less and has less rotating mass. Bob
