WHAT IS THE MOST POWERFUL CAM WITH OUT RAISING REV LIMIT MORE THAN 6200RPM ? IT SEEMS ALL THE AFTERMARKET CAMS WIND UP TO 6400+. I WOULD LIKE TO KEEP THE STOCK IDLE 115 LSA? NOT SURE IF THERE IS A RECOMENDED CAM. I HAVE 1.8 ROCKERS WHICH COMPLICATES MATTERS. I WILL INSTALL IMMEDIATELY WHEN I FIND OUT WHAT TO GO WITH. HELP!!! TIA.

you should shift at 6200 on a stock cam. thats what i did on both of mine and picked some e.t.
gotta raise the rev limiter of course.

i dont know if there is any cam that is going to want to be shifted before 6200 :dunno:

They all gotta learn....

But on a serious note, why do you want to turn your motor that high?

WicketMike, welcome to the Department of Redundency Department.

most aftermarket cams want to be shifted higher in the rpms, thats just how it goes. 6600 is a good number for many cams.

Stuck at work. All my stuff has to be in caps lock. Anyway, the main thing i am looking for is the bone stock idle. I was thinking about and '02 LS6 cam w/ my 1.8's and doing it that way, but I would like to get more bottom end torque that the LS6 lacks.( that's what I have been told) I need stock idle and stronger torque!!!! Pronto!!! Will do this cam/spring swap A.S.A.P. Thanks for all the feedback so far!

Try one of the stealth series cams....

Thanks, I have asked MTI and the dude seemed to be in a hurry from the time he picked up the phone,so I'll try some other time to see if they will earn my business. Thanks everyone for the replies!

i would say the old comp cam 212/218-.523/.527-114... ur 1.8's would bring the lift to .554/.558... any of the new XE/XER/TR cams have ramps too fast for the 1.8 rockers... that cam would make decent low end and pull hard to 6200...

LS6 cam lacks low end torque...Compared to what...Don't believe everything you've been told...

LS6 cam is a great sleeper cam contrary to what all the If big is good, then bigger must be better guys say...

If you want low speed torque, then you definitely do not want to go bigger...Torquer type cams can make great numbers in the 1000~5500 rpm range, with a small sacrafice up top...

But, that is the price you pay...Power up top, cost you some low end and big power down low, costs you some top end...

Until we get variable valve/cam/intake timing on the LS engines, there will always be a trade off...

Peace...Gman

If you want to keep your rev limit low, you need to narrow the lobe separation angle quite a bit and keep the duration on the short side. The intake closing point should be around 36 degrees ABDC (@.050") for peak power well below 6000. This will give you stump pulling power down low.

Something like 216/222 .530/.530 112LSA +4 degrees (108 ICL). This has an intake closing point of 36 degrees ABDC (@.050") which is where you want it for torque down low. HP peak should be around 5600 rpm and the motor should be done by 6200 rpm.

I make peak power at 5950 rpms.

Patrick G

iTrader: (14)

If you want to keep the stock rev limiter, you want your power peak to be at least 400-500 below the rev limiter. If your hp peaked at 5950 rpm, then you would basically be shifting AT your peak power. You want a little more rpm room between your power peak and your rev limter to allow your gear changes to fall within your best torque/hp window. LS6 cams might make peak power at 5900-6000, but they make best ET when shifted closer to 6400-6500 rpm. Short shifting is not good for winning races.

LS1tech rocks!!! Thanks for all the help... on my lunch break I will call Comp Cams to ask about the one mentioned. I need to ask them when they put the +4 on the cam, do I advance it or is it ground into the cam? I install things on the weekends, this will be my Christmas project. Will raise the limiter to 6,200, don't want to go crazy because of the lifters I have. I want to change them, but that is for later when I do heads. Plus, I thought that the hydraulic lifters " pump up" after 6,??? rpm. Thanks again for all the feedback!!

Patrick G

Stock hydraulic lifters are good past 7000 rpm. I recommend you having Comp grind the +4 into the cam so when you line up the dots, it should get you in the neighborhood of 108 intake centerline. You should always double check with a degree wheel if you have one. Keep in mind, you will need some pretty good valve springs, even with a 6200 rpm rev limiter. Remember, stock rev limiter is 6200 rpm. You won't be raising it. Something like Comp 918 springs would drop right in.

what about the asa cam. i never had a chance to dyno it before I pulled the motor. but it pulled down low and up high. I liked the power curve. I think the numbers went somthing like this. 226/236@.050, .525/.525 lift, on 110 lsa.. correct me if I am wrong. but i had that set at 6200rpm and it pulled all the way through the rpms. and also you can use the 1.8 rocker arms just need to compensate for the added lift it will bring. so with the asa cam it will be around .571 or so on both sides. and I have that cam and a sound clip of it if you want. B/c of the decision to go bigger I have no need for it any more.
hope this helps.
