Let me know what it takes to make 400 rwhp on an 02 LS1. I'd like to do it so I figure the best answers would be from the 400hp alumni class.

full bolt ons and a 230+ duration cam and tune should get you there on stock heads.

with heads your over easy. i think the best overall streetable 400rwhp setup is some nice ported heads and a 224 cam plus bolt ons.

Super - PM me with your full setup from spark plugs to intake, etc. Maybe we can figure out where the power is being held up.

See sig for numbers and mods. There are a few more guys making the same or more power than me with just about the same mods.

I got 400hp from a 224 Cam and stage 1 ported LS1 heads with FLP's/Corsa a few years ago.Then added a 12 bolt and it went down to 375hp.

Havent been on a dyno but I'm guessin right around that mark.

TEA stage 1.5s, TR224/561, MACs with custom ORY, LS6 intake, Yella Terras, and a ST3800 stall.

I went 11.41@119 in a 3550 lb car on radials on a 1.58 60'. +200 DA.

400 is easy, you should shoot for 475

c1 cam and mild headslike stage 1.5 or so from a local shop

Your 1 of 2 who have h/c headers that didn't make over 400rwhp though the stick. You just need to find your problem and you will pass 400rwhp easy. If you think it's the heads send them back we will send you a brand new set free of charge. However your poblem lies elsewhere IMHO.

Does 399 rwhp count??? Check sig below for mods.

I currently have my C5 at JPR (Joe Prince Racing) in NJ. The car will have 460+ rwhp. Joe get's these numbers with heads and cam. Send him an email to jprince@net-gate.com.

Here's my car:

02 SS T56, Hardtop coupe, Bilstein Ultra Suspension, Hurst shifter, CAGS eleminator with SLP LTs and 345hp airlid running an Airaid filter with a chromed CME out the back.
So that breaks down to an LS1 with LS6 intake and injectors and decent intake and exhaust setup.

I know you can get better peak HP out of other headers, but the SLPs are on there and they're staying.

I'm looking at about $2,500 or so for a budget, I don't think I can afford a head package, but alot of you are running at or near the 400 mark on stock heads and I'm told it's quite doable.

I am also planning a gear swap to better utilise the power. Still deciding on 3.73s vs, 4.10s. I'm not a quarter miler so I don't need the best setup for the 1320. I want a good all around performance car that will be fun on an occiassional SCCA Solo II event, driving the open highways of Nevada and the Sierra mountians...and also not to be f'd with at the stop light

I'm currently running an SLP STB and will add SFCs and perhaps other suspension mods, but let's concentrate under the hood for now.

Boltons and A TSP 231/237 cam made 401 through a 12 bolt with 4:30's.
