Hey i'm currently building a 6.0L iron block and i'm wondering if anyone has used this cam with good results.


408 Stroker
6.0L iron block
L92 Heads
OEM LS3 Intake
4.000" Manley Crank
6.125 Manley Rods
11:1 Compression Pistons
1 7/8" Kooks Headers

I'm looking for the perfect cam for my application. I want drivability over peak hp. Its going to be a daily driver so I want low end torque for fun around the city. It doesn't have to pass any kind of emissions. The research I've done seems to show that these heads like high lift, low duration, wide LSA's. Let me know what you guys think. Thanks

My buddy has a Comp 228/234 with XER lobes in a L92 block with LS6 ported heads.
That cam works great, idles good, is very drivable, and has great power.
I have the same motor with a 233/239, it is more of a beast to drive, great power, but too much for a DD. I think you are in the ball park with that intake duration.. For L92heads you may want go with more exhaust. +10 is a good number. 227/237

If I used that comp cam 227/235, do you think i should advance it +2 to help the low end torque. I want it to be fun driving around the city. And Thanks for your help

FWIW unless you specify otherwise they usually come advanced a couple * anyway. Look at the ICL. For ex. a 112LSA advanced 2* will have a 110ICL or if it was advanced 4* the same cam would have a 108ICL.

Sorry if you already knew this

227/235 114 is pretty common on LS3 cam only swaps. With your extra cubes and slightly higher CR, 227/235 113 with 2* of advance should have a high DCR and excellent low end responsiveness.

Sounds good. Predator-Z recommended a 235/247 114+4 for my application. Would that high of a duration be able to handle great drivability? Also I want it to be super torquey.

Anyone think this motor will make over 460RWHP with that cam in it?

Depends on the rest of your drivetrain. Wheels, tranny, gear, blah, blah..

You should make that number easy if your tuning is on par.

the 227/235 .614/.621 113+2 or +3

Yes.... it will.... and about 470+lbs of tq....... is this an auto or manual?

either way.....it should clear 460rwhp with ease...... but gain more low end.... +3.......

The other bigger cam is more top end oriented, max effort, perfect dyno cam.......It will shift your torque curve outward as well supply more overlap which low end may be soggy..... You'll see larger numbers on the dyno but from idle-4000 the 227 cam will be the ticket for a street car.....

With this cam Gfan knocked down 469rwhp/420rwtq on a 11.1 comp 6.0 with and A4 3200 stall...... so go figure...... Your adding 34 more cubes and a larger crank......

If your stuck on the LSL lobes: try these.......
For a excellent street car with more tq 227/235 .614/.624 113+3
for a more mid range and top end 231/239 .617/.624 114+2

Hey thanks for the info. I think I'm going to go with the 227 cam and advance it +2 or +3. I'm not sure. Where would the horsepower peak with it being advanced 113+3?

I think the shelf version of this cam comes from comp with 113LSA+4* ground in.
I run the same lobes, but 114LSA +4 and it is a great street cam, my engine only has 9.6:1 right now and this cam acts a little soft below 3000,yet really runs up top - revs to 7000 no problem, but I really like it for a regularly driven car. use good valve springs.

Hopefully the 11:1 compression in my motor will help the low end sogginess. Thats the last thing I want. I want high torque down low.

How low are you looking for? 2000 rpm? Do you go WOT at that rpm, or are just looking for crisp part throttle?

I agree with Bozzhawg on staying smaller if you are looking for stump pulling torque at 2000 rpm.

I normally wouldn't advance that cam to +3 with 11:1 CR just for overall balance, although the peak is only going to move down a 100 rpm or so with a 1* change in ICL.

No I just want crisp part throttle down low under 2000rpms. I want it to be fun to drive around the city.

I am building an exact replica of your setup (except for LS2 block). My cam: 232/240 XE lobes 113/113 LSA/IC +/-0. I don't have numbers yet. My car is strickly HPDE. Very little street driving and no drag whatsoever.

That sounds like a fun project. When you get numbers on that motor, please let me know how it comes out.

i tuned an 05 A4 GTO, ls2, with these heads and this cam. it made ~470/420 to the wheels.

TQ was way low. Did you find an explanation for that??

Torque sounds right from what ive seen. Stroker motors will make more torque but not stock cubes.

jegten

iTrader: (22)

actually, it is not low. it is good, and i was not done with the timing. other than an out-lier (or two) from the search i did, this is pretty up there.
