Pfadt Tri-Y Headers
FAST 92 (the 102s don't clear the cowl on c5s a lot of hte time)
AI 232CC 799/243s
BTR Stage 3 or 4 cam
Fairly inexpensive for the power you will gain.
Or splurge and get the MAST small bores and save on the ls3 intake manifold.

1) this is my first Y body, and we all know the mufflers are ran weird on them
2) mufflers- Corsa has no packing to begin with, which is why they sound the same regardless of age. It's all made up of tuned "baffles" that oddly NEVER have any drone. Exotic is the only way I can describe it. They "sing" more than sound like a muscle car going WOT.
But yes, I personally believe they sound different. More refined, so to speak. Not harsh at all.
What really sucks to know is that yeah, I've got good gains, but until I put a cam in with some healthy overlap, I haven't even BEGAN to scratch the surface of what these headers can actually do.
Once I have some aftermarket heads, and have a cam spec'd for them, I think that'll be the deciding factor on that.
Dave, two things:
Does it feel as fast as your Camaro even though it doesn't have near the power yet?
How different is it to only pull to 6k after being able to pull way past that previously?
Also, on H/C/I package here's a buddy that just did a set of TFS 220's w/ turned down LS3's, milled to 59cc's, stock trunnion upgraded rockers, Tooley spec'd 231/241 on 113+3, ported Fast 92 w/ an LS2 TB. Just dyno'd this week.

I'm kidding!
It feels a bit more zippy, and definitely handles better. I do miss the raw kick-in-the-pants from the Camaro though when you'd just punch it at 3500rpm.
Pulling to 6k or so isn't bad, as you can feel the power waning off anyway, so what's the point of going past it. It takes longer in this car to get to 6k than it did the Camaro to hit 6800, so I guess it's a wash
In a car like this, being so light and nimble... I think even 440 would "feel" a hell of a lot stronger than what I came from.
I think I very well may pass on the Mast heads. I don't know yet. I'd really like to get a set of Chris Frank's (Frankenstein Racing Heads) CNC'd and hand finished TFS. Either him, or something from Darin Morgan... I just don't know what Darin offers.
I DO know that if I go with the 434, it'll be topped with either stock or RHS LS7 heads and those WILL be coming from Darin.
So my 353/366 guess was fairly close.....Car sounds really nice....
Your description of how the C5 feels is on point and a quick hundred more horse from a head/cam combo will keep ya having fun for a little while.

Good numbers ^^there^^ for sure. I did it with less head, and less cam...

I'll be able to see Chris Frank's port work first hand next week! My heads should be completed, finally! My conversation w/ Chris earlier this week really pumped me up when he said my LS7's should flow 410 I/270 E!!! Darin and Chris are both top notch porters!

My thing is if I stick with the 5.7, I definitely want an aftermarket casting. I know Chris likes TFS Porter's Castings. I have no clue what Darin uses for a head, or if it's send in what ya got. TFS 220's might fit the bill with him then.
Either way, you're going to have a ridiculously nasty build, that's for certain!

AI offers ported TFS heads. http://www.advancedinduction.com/LSX...0ccTFSHead.php
I really wish I could come across some used ETP 215's, but I'd want them checked, as it's my understanding some had porosity issues. Or maybe that's the PI heads... Idk.
I'm worried with the small bore LS3's I'd lose the "snap" that made it fun to hold 3500 for a sec in even 3rd gear, then just floor it and enjoy feeling the torque.
I'm fairly certain if I stick with a 346 it's going to have Cathedral ports.
Why do something crazy... like the TFS 205 heads and a big *** cam. Lots of compression (58cc chambers) and 205cc runners with 300cfm capability. I know Ed hates them, but it's basically like putting AFR 205s on the car with a lot more compression.
Throw the Hellion 244/248 in there with 205s. I bet 500rwhp. The compression and small runners would make up for any laziness due to the later IVC. And no flycutting... 12:1 CR with Cometic .040s and more than stock PTV.
Honestly, I kind of wish I knew about them last year. I would have seriously considered them...

Where in the world are you seeing a TFS 205? I haven't even heard of one of those since about 2009.
I want at least a 215 intake port this time around I think.
