One of buddies had one in his 02 ss. I thought the car ran pretty decent, but I just want one a bit bigger. I was hoping to get closer to 400rwhp by using a 224/230 xer comp cam

Nothing weaker than TRex here
Cerealsly. The LPE GT11 is an awesome cam. For low duration. It is kind of aggressive on springs, and it does like 6000rpm shifts.
Ive had a ls6 cam before, but never a hot or asa cam.
Although i hear they make for good power and can even use ls6 springs.

A friend built a gmpp motor which would of coarse mean all gm parts. Gmpp cnc'd ls6 heads and the grand am cup cam. It made a little over 450 to the wheels and probably could've made more with more/better tuning. That was on a ls6 intake.
Then there's my car. 426 rwhp on a crate ls6.....stock ls6 longblock. Gm cams can make some good power. I think knowing what we know now a hotcam could reach almost 400rwhp.

I don't think it's possible. A hot cam properly tuned against same car with a 224 with proper tuning will not make close to the 224. Just saying. Its simple mathematics.

Thanks for all the replies. I see there are still mixed feelings on the GM Hot Cam. While I still have a little time before I tear into my engine, this is plan A:
AI 241 cating 219cc CNC HCR Heads
GM Hot Cam
TPIS Modded LS6 intake (To accept 90mm TB)
Pacesetter LT Headers, catless w/ 2.5" piping into Spintech Super Pro Street mufflers
LS7 Clutch/Flywheel kit
3.91 Gears.
As you can tell, I am going for all GM, even though I know I'm probably leaving some higher hp #'s on the table. I think my 04 GTO will enjoy this setup. Feel free to let me know what you think of this, better yet if anyone has done a setup like this, how was it?

you would be suprised at how some baby cams smoke bigger cams at the track.just because one cam has more intake dur. than another doesn't mean it will outpower the smaller cam..

IMO, why not just get a custom grind that's very similar to the Hot Cam 219/228 112lsa cam? You could go with Comp Cams Xtreme RPM High lift lobes for a little added lift (218/228 - 563"/.571"), and if you want to go a little more aggressive go with XER lobes(220/228 - 581"/.588").

On a somewhat similar note,
are there any other off-the-shelf cams that are valvespring-friendly over the long term?
Seems to me that even the "low-lift" cams of today require semi-regular attention to the valve springs because they have an aggressive enough lift.
Would one be stuck going with a custom grind if they wanted a low-lift performance cam but didn't want the hotcam?

A bolt on frc with a 4k stall will run 11s
It might be worth 30 whp to swap to a hotcam from stock...why not take many years of r&d and use a cam that wasn't designed 15+ years ago

May I suggest that you revise your train of thought, that kind of thought processing can damage your life a lot.
