that cam is far too small for LS-6 heads... stage II at least... I'd say stage II ls-1 heads would work just fine.

 

Is this the same place where you learned that 6.0 heads raise compression? Do some research on ls1tech.com.

BTW according to Thunder's website: Here are some mods they listed on top of what you have that helped that cam to make 398 whp. (ported throttle body, ASP Pulley, Aluminum Flywheel, and Carbon Fiber Driveshaft). Less rotational mass does make a nice difference, and having ALL the info makes a difference too. Also, I'd bet this was dyno'd on a nice cold day. Also is it SAE corrected? Even if you do get 400 rwhp out of it w/stock heads, no head in the world will make an additional 100 whp.

TSP has some dynos on ls1tech of their magicstick cam w/Stage 2 5.3 heads. Again, this is an over .6" lift cam and it is still ~50 whp shy of the 500 whp mark. I have seen with my own eyes a C5 M6 with a hugh cam (again over .6" lift) and worked over ls1 heads among all the bolt ons and tuning make ~460 whp. Nothing wrong with that, but it isn't 500 whp.

Ya, I'm an ****, but at least I'm realistic. Good luck though.

 

And for everyone that reached 400rwhp with that cam there are 4 that barely made 380 with it.

As far as reaching 500rwhp all motor, stock cubes ... as far as I know if you do it, you'll be the first ... especially with that cam ...

 

Greed4Speed - No greed, i just think i got confused. Not everyone is perfect. "ported throttle body, ASP Pulley, Aluminum Flywheel, and Carbon Fiber Driveshaft" Ported Throttle body is done... did nothing for my car, didn't even bother to list it. Asp pulley is on the way. I don't like aluminum flywheels for street driving and i can't see a carbon fiber dryshaft being that much more beneficial seeing a stock ls1 dryshaft is light as hell.

V6toZ28 - Better search some sigs, i just saw one with 384 (untuned) with my mods. Wish i could remember his name. I'll let ya know if i find it. I am over the fact that 500 might not be realistic for what i want to do. BUt i would like to be somewhat close. I guess we will have to see. At least i got my answer, stick with my stock heads. I realize now that the cam is not big enough to go bigger so stockers will work fine.

 

With that cam your not gonna hit 400 with good heads you will be around 410ish. The best heads for a 224 cam imo are cartek heads ported for the 224 cam. If not then a 5.3 stage 2 port wich will raise the compression alittle wich will be good for the juice later. Afr's new 205cc's are looking good right now also but might want to wait and see some more results first.

 

Yet more info for you.:

2nd guy to post.
399 w/ stock heads, tuning and bolt ons, and 416 w/ stage 2 5.3. Same cam. I was talking to a guy today that ran that cam and he makes low 380s tuned, w/stock heads .

From what I've seen the pulley won't show gains on the dyno, but will at the track.

And you may want to take a stock MAF when you get tuned. The tuners I've talked to won't touch a car with a ported or aftermarket MAF.

BTW, the smiley face after the 6.0 head comment was to show that I was just messing with ya. If I was really being an **** I'd have never said good luck. I'm one of those information ****** that researches the hell out of something before purchasing it for my car. Then I'm sceptical about gains until I have proof. lol

 

well thats good to know, but i also believe every car is different. and my car has already proven tons of people wrong on this board. So just a lil thoughtful hope for me. Thank u for ur information however. I did get an answer after all this and i appreciate this.

Why is that?? I'm really confused. Enlighten me, please.

 

way back i posted a thread asking what i should run in the 1/4 mile stock, and then with my existing mods at the time. I also asked what kind of mph. I got people telling me 13.6-13.9 stock cuz i am a "Heavy Vert" and telling me traps will only be at 106-107.. when i pulled off a 13.2 at 109 with a 2.1 60'. Thats why i believe every car is different.

 

In my experience the 224/224 cam usually nets a rwhp in the 380-390 range with stock heads on a car with all of the bolts and well tuned, but many factors come in to play with dyno numbers. With good Stage 2 heads the 224/224 cam is usually good for 420ish rwhp, I've seen lower, I've seen higher. It is a good all round cam that has good manners on the street and will net some good numbers at the track.

StylezZ28- I would get rid of the MAF and go back to a fully stock one, get a line lock and heat those Nitto's up and get your 60' down to a 1.9-2.0 and you can hit high 12's without the cam, mid to low 12's with the cam. Start planning/saving for a 12 bolt.
If you want some good heads for your setup I can help you there.

 

6 speed with LT and DRs should be in the 12.7-12.9 range with a reasonably competent driver ... nothing special about 13.1 with your mods even for a "heavy" vert.

 

I would give the people at kartech a call... you CAN see 500rwhp from H/C

 

Wow, what a poor attitude. My point was 13.2 STOCK @109, 13.1 is a burned up clutch, crappy 60' and a dragging y pipe all the way down the track. Sparks flying out the back. I even got kicked out that day for the ypipe and they wouldn't let me run open headers.

Thanks for the offers and info highlander and Demon. I am just going to have my guy do the maching on the stock heads. Get it fully tuned and see what she does. going to prob be a winter thing anyway but want to start planning now. I may hit up the track soon on a wednesday and see what she pulls. I really wanna try and get a 12.5-12.6 out of it w/o the cam. I think she can do it with a real sweet 60'.

I will look into the stock maf idea. It didn't seem to hurt the car at all when i descreened it and gutted it, but i will do what i can to see the power gains.

Thanks again.

 

My LS1 ran this stock..except my 60 was a 2.2
With a TSP Exhaust I managed to run a 13.09w/a 2.2 60@109

 

That cam will easily get you to 400 rwhp with ported heads, LTs and intake. I have the TEA 5.3 stage 2s with Jet Hots and running full cats and muffler and all accessories easily reached that number. I don't however expect you to get anywhere near 500. This is a cam that will smog even in the Republik of Kalifornia. With some time with LS1Edit mine idled like a stock LS1.

Assemble and enjoy it.
