Who Knows Best About Ls1

HI EVERYONE.. i have a 2002 Ws6 sixspeed with LT headers, exhaust, airlid and TB.. Im looking to get a good head and cam combo.
Im thinking i might have about 360 hp now.?

Is it possible to get an extra 100+ with the H/C?
Who knows about a good setup? (my car is driven daily).

You probably aren't going to be looking for 450+ RWHP on a daily driver.
It can be done, but I wouldn't personally consider a car like that a daily.

Do plenty of research on cams and heads. Call sponsors and ask a TON of questions.
Your options are damn near unlimited.

Also, don't get too caught up in peak HP numbers. Cars that make power throughtout an entire powerband can be just a mean as those higher peak cars.

I'm seriously doubting you have 360hp from a bolt on car. Even so, like Luos said, even if you could do 460 from a head/cam kit the cam would have to be big enough as I doubt it'd be daily driver friendly.

one things for sure, youre not making 360 rwhp, maybe 340 at best.
if you want to make mid 400s in the h.p dept and have it daily driveable, youll need a cam and supercharger.

Ive seen it done once on a 01 m6 ss......well close i think it was 358 with full bolt ons and freemods

well with a FAST 90/90 also. I have a couple friends that both dynoed over 450 RWHP and over 400 RWTQ, with H/C, LTs, X-Pipe, and FAST 90/90 and of course tune. so it is very possible, and that is a MS3 cam on both, which in my opinion is very streetable.

but def. agree with Luos, don't be dependant on peak numbers.

I have seen 365 RWHP from a 2002 LS1 with headers being its only real mod. It dynoed 350 RWHP bone stock. Its rare, but not impossible.

Most likely though, you are right with the 340 RWHP range guess.

ive heard of a c5 corvette going 400/400 on a m6 with full bolt ons.....but yea i know the motor is a little better........still though......its not beyond belief.....i wouldnt bet on it though unless u get a dyno on it man.....The guy that sold me my first z28 told me it had 375hp......and all it had was a dumb ass programer lol....

I didnt know shit about cars and tried telling some veteran lt1 guy I had that much and he called me the fuck out haha!
