i ran 12.1 @109+ with the mods in my sig less the LT's so i guess that proves u wrong

And IF you like the NASTY idle the Hot Cam has like I do, but you want more power, like say a 224 cam gives you, then go with new rockers like I did. You need to upgrade the valve train anyway if you want to run the higher rpms (which is where you'll see all the new hp a cam gives you). It's another point of view to consider.

You wont make a hotcam turn into a 224 w/ rollers.

Interesting opinion. I gained 15-20rwhp & shaved about a 10th off my et with my Hot cam, and got the same all over again from 1.8 rockers that give the Hot Cam .555 lift. And to date I run stock heads. So I guess I disagree.....
i wasnt saying that, i was mocking the other guy who said that..........

Hi Folks
As pointed out, everybody has different requirements. I have the 02 LS6 cam and the GM ported LS6 heads, the combination is not bad. The car pulls hard after 3000 and once the car goes into second and above, the engine never drops below 4000. To me it is not bad and now I have a major traction problem with the stock tires.

No it's not the most powerful and best performing cam on the market, but that's not what it's all about all the time...

I know, I was trying to capture both sentiments at once. Sorry!
As for why do rockers + a HC, I like the added piece of mind that after market rockers give me. I have NO faith in stock rockers @ 6500rpm (or above). So in my omion, if your installing a cam that will spin that high, you gotta replace them.
And my combo seems to be pretty good. I plotted it against an AFR & PP & MTI dyno chart & came out last at the top end because of my stock heads, but I was right there until 5k. Once I get my heads reworked, I figure I'll do better. And they were all running 224 type cams with LSX intakes. I made this chart while researching which heads to buy.
I'll post the chart again here for anyone that's interested. This chart doesn't show the 475HP MTI kit dyno, but it was a little above mine all across the band. Note that I was on a chassis dyno with my A4 so I didn't get to nail it until after 3k.

If you are looking for a good cam upgrade, but dont want to go big, look at a 220/220 cam, or even the TR224 on a 114LSA.
Here's my input: do some research and find something you know you're going to be happy with.
Call a cam grinder and tell them what you want, see what they say.
I've had my C1 (222/222) in since June and I love it (just another small/reliable cam option...).

I have the hotcam in my car... It was mostly the problem of having my engine rebuilt while I was overseas, and the shop wasn't very LS1 knowledgable. I figured they couldn't mess up GM part numbers, etc.
My car is pretty tame, I have no real mods (JBA shorties, ORP, 3" catback, lid). With tuning I got 351/348 thru 4.10s on 17x11 ZR1s, and I'm pretty happy with that, with stock heads, stock ls1 intake, stock throttlebody.
About the Hotcam, you do need tuning to really see the power out of it. I picked up 30rwhp and 20rwtq peak and even more low-midrange.
BUT I will say this, the Hotcam has a good sound and is very low lift, you won't have much wear or tear on the valve train. Those are the good things about it. But for almost any application there is a better cam out there. I would only recommend this cam to someone who wants a cam sound and still make 100,000 miles on their valvetrain, and doesn't really care if he gets 20rwhp or 60rwhp out of it.
I'm switching to either a 224/224 @ 114 or 220/220 @ 114 (making a CA smog legal setup)

there are big cams that give great power under the curve, in every area over the hotcam...if youre just doin it for sound then get a hotcam and leave it untuned...but if youre gonna go through that trouble then why go for such a small cam...its kind of a waste unless youre doin it for emissions reasons, but thats my opinion, and opinions are like buttholes
