Dont have a tvs but when you say big powa hope your talkn about 350whp with lots of supporting mods like cooling, e85 or potent meth mix. For if your funds run dry just buying the tvs then you will be at the 300whp wall for awhile but in do time i assume you could keep throwing supporting mods at it to slowly make more. Either way you go, just research it and spend wisely.

I see you're from Houston! Feel free to head over to www.GMofHouston.com
We are always willing to help.
350--400 is definitely in the upper ranges of the TVS's capability (at least on the LSJ), so you're going to need to do things right instead of looking to only do the bare minimum.
You can safely hit ~275whp on the stock intake/exhaust with some larger injectors and cooling mods though. That is about the lowest power you can expect from the TVS on the stock pulley. Definitely a good starting point if you plan to start from scratch.

If you want to make good power on the TVS you will want a full 3" exhaust, and to be tuned on E85 or meth if there isnt E around you. But as Pyros said you can start on on the stock pulley and stock exhaust with 60 or 80# injectors and a tune and always add to it
I have the pistons already,head will be here saturday

Supporting mods are over-rated. All you 100% need are larger injectors (60#s+) and a tune. You don't need to waste your money on this useless stuff to make the car quick. Take advice on the people that have done it, not the majority of these people.
The only way you will make "big" power on a TVS is with E85. I wouldn't even bother on pump gas, be a waste to even buy a TVS.

how to build a 400whp tvs lsj.
i did 380whp on mine {yes darky, 380}
3inch intake
tvs
2.6 pulley
80, or 98lb injectors
return system
255 fuel pump
surge tank
bosch 044 pump
SC specific cams
supertech 78lb valve spring kit
ported head, intake and exhaust side
neutral balance shafts
1 3/4 or larger primary header with a 3inch collector. burns stainless or equivalent
3 inch exhaust
3 in down pipe
bad ass tune
e85, or 110 octane fuel
a good heat exchanger. griffen core.
for added measure to hit it. 10.0:1 - 10.5:1 C/R.
you might be able to do it on stock compression
