I want a "Low end torque cam" for my 04 4.8L
 

Stock torque converter? If so, none of the above. Get a Cam Motion 205/212 high-lift cam like the one in my sig. :D

Alternatively, there is a GM part number (12574519) with almost the same specs, and costing around $250: 204/211, .520/.520, 116

i got a comp 212/218 that i might be selling. let me know if your interested

Sorry I always forget the TC, it is stock with no plan on upgrading.

fogle04, pm me with a price please

I have the Comp 206/212 on a 114lsa in a 5.3, so it's really tame...no lope at all. It's great for a daily driver with the stock stall and a definite improvement over stock. The Comp 212/218 is a very popular cam from what I've learned here and at ls1tech, although I don't have first hand experience with it.

I assume that a 6.0 cam out of the SSR would be a really nice cam in my 4.8, but will this cam be more torque or would it be an all around great cam for my daily driver. Will it work in my truck? I have seen many different cams on ebay and the latest one is out of a 05 GTO LS2? GM bumpstick would be really nice on the wallet, just need to know if they will work in my LS1 block? But I am not limited to just GM. More bang for the buck is what I am all about.

If you don't mind me asking, why? I have a 3500 Stall with a 2.5 STR and have PLENTY of low end. I smoke my tires easily from a stop or a roll with light throttle input. I have a 4.8. I daily drive my truck with the stuff in my sig. The only thing I need to do is get another tranny cooler and I'll be set.
IMO if you're doing a cam swap, with all of the work involved do it right and get the cam you want.
Philip S. ;)

The LS2 cam won't work in an LS1 based motor without swapping cam sensors and parts under the front cover to LS2 specific parts.

The LS6 cams are notorious for having a very soft low end, but nice upper rpm power. If you put a LS6 cam (either model) in a 4.8, expect the low end to suffer greatly with the stock converter. The LS6 is anti-torque.

To make more torque, you will generally need an aggressive lobe with short advertized duration and high lift. The idea is to snap open the valves and let as much air in as possible, then close it quickly so it can make make higher cylinder pressure.

with a cam of that size it would seem difficult to tell if you have any low end. a 3500 stall doesn't get you to the low end.

as for picking your cam Suddog, there are none that will give you good low end torque from a 293 cube short stroke engine. the stock converter isn't a high enough stall with the stock cam let alone going bigger. the comp 206/212 is probably in the area of your best shot at having any decent low end torque. something like naked av is running would also be what you're looking for.

not sure if youve read these but they are good discussions that will answer your questions, just remember they are using those cams in a bigger 5.7 so it will lower the power band in comparison to a 4.8 but the principales are the same.

About the converter thing, if you plan on getting a cam that creates alot of its power off idle or down low it makes no sense to get a high stall. The tcc is there to put you into the rpm range of a larger cam, so with one that creates off idle power you would be stalling right past some of the power band, less area under the curve. A big stall doesnt create power down low, matter of fact it will only multiply torque once near the stalling point. For what your looking to do I thing your on the right track in picking a cam and wont need a higher stall. Look at the specs on the stock cam, read the articles then put the two together and you'll have a picture of what cam you want.

Yeah LOL. My fault I worded that way wrong. A Stall with get you a lot of power of the line is what I meant to say by jumping up the RPMS to where power is at it's greatest. Wow, I bet yall think I'm an idiot now ;)

i knew what you meant by it, but wanted to clarify it for others that may have taken it the wrong way.

i have a cam motion 205/212 548/540 114=4 i would love to get rid of.200 miles on it

:thumb:

This is prescription for your problem right here.

did you dyno with this cam any more info you can give us? Looks like a good choice for what he wants to do.

i didnt get my truck dynoed with this cam,but i put in in , drove it for a couple of weeks and then i got a great deal on a bigger cam to go with my whipple.this cam was real stong on the bottom end,pulled hard to about 5500 rpm

Mine gave me 15 RWHP all over, 20 RWHP peak, on back-to-back dyno runs, with the cam being the only variable changed. This is the same cam.

Best part of the cam install was the off-idle power....'holy shit' :eek: is the best way to describe my reaction. I am very happy with it.

Kim Allen, PM with a price please.

:stupid:

OK Cool. :cheers:

Naked, do you have the dyno sheets?

Would this cam be good for my 5.3L? Where can i get a cam motion cam? Also the alternative GM cam, would that be a good stealthy cam that will make decent power?

Im in the same boat as Suddog. Would the Comp 206/212 .551/.522 112 cam and a trailblazer verter be a good combo?

the 206/212 cam doesn't need a verter to the best of my knowledge. But It would help you take off a bit faster.

The alternative cam is from a SSR which is an LS6 cam which will not be a direct swap for your cam. You would have to move the cam sensor and then change the chain and stuff under the chain cover to ls2 parts. All this is to the best of my knowledge.

www.cammotion.com is where I found the info on their cams. :drive:

Ok guys I went with Kim Allens' Cam Motion Camshaft. Now comes the hard part...putting it in. Anyone know of someone trying to get rid of a set of LS6 or 918 springs?

Damn, I should have checked this yesterday, I have something I think you would have liked. I had the 206/212 on a 112lsa with +4*. Anyway, I think a tb stall would really help it. my times went down with the cam a little, but my MPH went up a good bit. Anyone else looking for a similar performance cam pm me. :cheers:

How much compression does the 4.8L have? 9.0 to 1? Thats probably whats killing the torque, not enough compression. Should be 10.7 to 1 like the z06.

4.8L is what's killing it. that's hardly enough cubes for a truck.

:stupid: Needs more displacement. 4.3 v-6 is .5 less thatn athe 4.8. The 4.8 is .5 less than the 5.3. Big difference. Even withe the two cylinders missing, tThe 4.8 is just too small

...there's no replacement for displacement :devil: ...

:stupid: :rock:

Go directly to cammotion.com to get a cam from them. And yes, that GM part has very close specs....I would consider that one as well.

Don't have the dyno sheets, they are on a web site, all I have are the raw DynoJet files and my computer's acting up right now....:(

I think you're going to like it.... :secret:

I have a lady on ebay trying to sell me a set of springs from a brand new set of LS6 heads for $70. Will these springs work on my 4.8? Are they direct replacements?

I'd buy them new (GM P/N 12565117), you can get them for ~$5.50 each, or $88 for all 16 of them. Springs are too important to be messing with used or unknown.

Alternatively, I ran across this part (GM P/N 12499224) that might actually be a kit containing all 16 LS6 springs. If someone can verify the part number....it's only $44.80.

Naked AV,

Tell me all about your cam. Where is the true power at (rpm)? :burn::burn:
I have 3.73 gears in the back. Are you still in CA? If so does your truck pass smog with the new cam?

The power is from 600 RPM's all the way to 6000 RPM's, when my driveshaft likes to come apart. :lol:

Seriously, the power is all over. And yes, I'm in CA, but there will be no problem passing smog, though I don't have to do it until 2008.

I did a part number search and I am glad you are on here. I can order them from my dealer for 2/3rds her cost. Thanks! So did you put the cam in and then the blower? :cheers:
