LS6 Intake, Important?
I want to build a 400 - 450 RWHP LS1 for a project vehicle of mine. I want to accomplish this by doing a semi aggressive cam and some cheap heads, like maybe the heads edlebrock is suppose to come out with. I also will have decent mid tube headers and an X pipe true dual exhaust system. Will this alone be enough for my goal or do I need get a new MAF, TB, and intake manifold? The engine is from a 99 Trans Am.
all 01+ cars have the ls6 intake regardless of trim. and yes your a dumbass for not taking it

ls6 intake, TB, and pulley are worth alot more on a h/c combo, big or small, then some people realize.
Keep in mind that im looking for 400-425RWHP and nothing more. The engine is going in a car that weighs 2300lbs and I dont want more than 425RWHP because of traction variables. I feel like sometimes people give advice to get the most out of a certain set up, and that isnt what I am looking for in this case. So will I need Heads, Cam, TB, Pulley, and manifold to reach 425rwhp or will that set up most likely result in more HP?

if its going in a 2300lbs car just keep it stock. 350, 400, or 425rwhp your gonna have traction issues. dont kid yourself in thinking that 400rwhp is a "safe" number.

I guess the fist hp quote was a typo as I had 425 in my head the all along. I have seen these cars with LS1 with the power I stated and they can be configured to hook up decently, however anything past that and your looking at broken rear ends and no traction. Forget the traction issues with the car, lets pretend we are talking about only the engine. Do you have an answer to my question?
or you can do it cam only with large cam and stock heads. it all depends on the type of powerband and application your looking for.
