With the ported heads you should be right on target. Without the heads through a stalled auto that 420 is going to be kinda tough. And for the price of the TPIS LS6 intake i would just look for a used Fast, you could probably get a whole 90/90 setup for about the price of the TPIS intake alone.

And unless you really want to get the last horse out of the setup you could probably save the money of the roller rockers.

And did GTO's come with 799 heads? if so they are the same as 243's.

I would keep the stock rockers and spend the money on other things. Also are you buying a modified ls6 intake for $850 and a 90mm TB for $550? If so why not just get a fast 90/90 combo... http://texas-speed.com/shop/item.asp...d=646&catid=73

Yes you can purchse a FAST intake for the same or less than the modified LS6 intake...if your going to buy an intake that would be a better use of that money...I think that you probably will hit 405-410 with that combo...you will need a set of heads to hit your goal...If you use the money for the FAST and TB to get a set of heads and use a stock LS6 intake you will probably hit your goal...my dailey driver is a heads/cam bolt ons car that make 452/418 with a LS6 intake....good luck with your project.

persoanlly id just do and ls2 intake manifold it take a bit of work to adapt but i think its better bang for the buck.

Okay so i dont need the rockers? And ill buy a fast intake and either get a good set of heads or some used 243. Oh iam a 04 gto i didnt put that on sorry. What do you guys think if i just skip all this and go with a procharger, what do i need to be go along with it if i wanted to go with this.

A pro chager will get your about 125-150 hp using the low boost that is required to work with your stock pistons....that is expensive HP considering the cost of the pro charger for those gains....forged pistons will allow you to cank up the boost and make larger gains..that will make a more attractive HP to dollar ratio ... there are a number of ways to make HP you sound like you need to figure out just what you want to accomplish.
