Will this setup be decent, and how much power? i came across a gto ls1 with 23 k on it. it has ARP rod bolts and heads studs already on it. i have set of stage 1 PRC ls6 heads. and a tr224 cam on a 114.
iam planning on puttin an STS kit on the car and running between 7-9 psi.
my ?'s are will i be ok running that kind of PSI on the motor.
how much higher on PSI can i go. with out to to much risk on hurting the motor TO MUCH
and how much power do u think i could put down wheel.
iam going to be using thicker head gaskets and a intercooler with 60 lbs motron's
thanks guys

The PRC LS6 heads will increase your compression if they were milled, which they probably were, increasing the risk of detonation that much more. A set of stock 6.0l heads would be better, safer and can be had cheap. Plus, you would make some money from selling the LS6's.
Running thicker head gaskets will lower compression but will also change your fuel 'quench' area which will do more harm than good.
I wouldn't do the VIC Jr. intake on a stock cube motor. They actually showed a loss of power in NA applications on stock cubes and wouldn't yield that much more power on a stock cube, stock internal motor. It would look cool, or different though.
Save the money on the Vic Jr. intake and spend the money you make on the LS6 heads to buy 6.0l heads and a methanol system.

weeeelllllllll these heads arent milled. and the car is def gonna be dyno tuned. and arent the 317 heads basically the same as the ls6 heads?
and how does the vic jr do wth a forced induction car

LS6 heads and 317 heads are not the same...and I agree with SS above that your best bet would be to sell the LS6 heads, pick up a cheap set of 317's, and work from there. If you are set on keeping the heads/cam setup listed above just make sure you have enough fuel and watch for detonation if your running pump gas. I would say with that heads/cam setup (if its keeping compression in the 10:1 or higher range) dont run more than 7psi or so as you would be pushing it. Also, look into a meth/alky injection kit for safe keeping. As for the STS kit, make sure you read up on all of Zombie's threads so you can see everything that is needed to make the kit work properly. If I were spending the money I would get a D1SC package, APS TT setup, or a Maggie setup, but thats JMO. Good luck with your build though and let us know how it turns out!

yeah iam goinna stick with the PRC ls6 heads. they have not been milled nor do they need to.
so u guys are saying dont go above 7 psi with out meth injection?
how much power would this setup bring me. with the cam and heads and 7 psi?

I would say close to if not over 500 rwhp depending on how much your stalled A4 eats up on the dyno. If you were an M6 id say def over 500 rwhp, so you should be in that range. If the LS6 heads are not raising your compression then id say yes max 7 psi to be on the safe side with pump gas and no alky/meth injection.

damn i was looking for more like 600 with 7 psi. so with heads and cam and boost ill only out down that much. i know people with just heads and cam puttin down 480 - 500 wheel.....
kinda makes me a lil depressed BOOO lol

run the ls6 heads with a thick head gasket and try 8-10psi with a good tune. and plent of fuel. alky would be a good idea at some point or if u can get e85 even better. check into that cam it might be better for a blower but either way FI will make power for you.
600 rwhp is a little optimistic but if that is your goal as stated above your going to have to run around 9-10 psi to get near those numbers. In that case you would def need to look into alky/meth injection or higher octane gas. I think you would be really testing the limits of the stock shortblock though if you were to push that much boost, JMO.
The ls6 heads are the wrong heads for boost application. If you lower the compression your goal would be more realistic. The tr224 is great cam but it's small compared to most cam now days. You have to rememeber most guys making 480-500rwhp don't have stalled auto's and have cams with a 600+ lift cam and some high end heads and a fast intake. Like stated with your compression you won't be able to push more then 6-7psi of boost safely.
