    I'd go for some different heads. Isn't the fast setup over 1.2k?

    Nope, you could get a set of 243's for cheap (ls6, ls2, new trucks). Not sure how much of an upgrade it would be though. Would only cost 400$ or so. I really don't know what cheap heads to recommend for you on an ls1. if you had a 4" bore motor the easy choice would be l92's for about 600$

    if you got a fast you would need a TB
    The gains that would come from that would not be worth it for the price
    Unless you found a used one cheap, the ls6 intake should suit you fine.

    Your LS6 is plenty good even though you have a cam. Yes you will pick up power with the Fast but price is up there. Since you have a cam putting in some gears would be a good option to take advantage of that top end power. Also a exhuast cut out with the electric opener is not a bad mod either. Your going to get advice doing several different things but i love the fact i have gears and i could only imagine puttin in a cam and really taking advantage of it by being in my power band longer and getting there quicker. The exhuast cut out will give you a good amount of power as well, with the electric opener it will only get loud when you want it. Either way im sure someone else might have a better idea, GL.

    I'm not really in love with the whole temporary gain thing, but the 1+k you could spend on a fast setup would go a looooong way with nitrous..

    I have never seen a cam only hot-cam car make almost 400rwhp before. I have never seen one make even 380rwhp on the dyno I tune on.

    "The cam specs on teh LS1 hot cam is .525" intake and exhaust lift with 219 degree intake duration and 228 degree exhaust duration @ .050". It was tuned by Jeff Creech in 2003 it has alot of timing on it."

    Since you mentioned Creech, I posted a link above you might want to read about. I will second what Frost said, I highly doubt you are making 398 with a hot cam, 368 would be closer to accurate with that cam.

    You dont think the MS4 is a little much for what he's asking?

    You'd be surprised; with proper VE tuning the MS4 is usually more streetable than the ever popular trqr2. The G5-X3 on a 114 is another larger cam that is very very streetable with good tuning. Cams in the low 230s on 111-112LSA's believe it or not tend to have more negative street manners.

    you get the m4 if your all ready making 398 hp that will put you well into the upper 400 range with just the cam ,

    Not a big Jeff Creech fan because he had done a few local GTO's here in the Tidewater area and their owners weren't too happy with the tunes. One was so bad the guy went to HPP Tuners U myself and now does tunes for our Goat club. Find a local shop or have Frost knock one out for you after all of the latest mods are done.

    ^^^^^^^ Yeah I agree with the Creech comment. I used to live near Durham NC where Creech has his shop and have seen his phucked up work. I know of a guy in Greensboro who had a Creech tune and it was so lean his motor blew a couple months after Creech tuned it. A few here may get my reference but you are lucky he didn't wreck your car. Fastpoon is not on this site so it may not be common knowledge here. I wouldn't let that fatass near anything I have.

    I hate to rain on your parade but Frost is right too that car should dyno in the 360-370 range.

    Off my rant now but you may want to have your tune looked at to be safe and 4.11's would definitely be a cost effective way to wake you car up....
