You want the heads and up, there's a lot to it, but it's doable.

so basically all of that, choosing one of the upper and lower intake manifolds?

 

20% is the standard assumed drivetrain loss for these cars. So 180 * 80% = 144 whp roughly. Seems to work out about right- the 200 crank hp 3800's do seem to actually do about 160 at the wheels; and the 240 crank hp SC 3800's seem to do about 200 to the wheels bone stock.

 

alright cool. lol

can anyone assure me on if thats all i need for the top swap?

 

get the headers instead. they look so sexy, and i bet sound just as nice.

 

they have 3400 headers? and im not looking for sound right now, just want more power

 

whats the actual power gain involved in this? i just seems like its going to be expensive and labor intense for the hp gain.

 

^^^ I agree with what he said!

How much power can you really gain from this? The 3500 stock vs. stock make 31 HP more than the 3400...so buy just putting everything from the head up onto a 3400, how much will that really get you? I would guess about 15HP, maybe 20 HP if you are lucky. And 30 HP is out of the question considering the 3500 itself makes that much more, so just swaping the heads up of a 3500 to a 3400 isnt going to give you full power of a 3500.

This sounds like a really expensive, and labor intense job, for not really a ton of HP gain. You could probably buy an entire 3500 for what this will cost...or better yet, do an L67 swap.

 

okay so how much am i talking for just headers then?

and is it wrong that i can keep up/beat my buddies G6 with the 3500?

 

Have you ever raced you buddy in the G6, or are you asking the question?

Depends on the year of the G6, the old G6 3.5L's did not have VVT, and only made 200 HP (which, depeneding on what your tune/ intake did for you might be a reasonable assumption, that you could keep up with him)...the newer ones with VVT are making I think 221 HP (which I really don't think you could beat).
