Hey guys. I know these cam questions have been beaten into the ground, but I was wondering if I could get your opinion on this. I've got a 2002 Yukon that really wants to have a bit more growl and umph. This is my daily driver and I don't want to sacrafise milage a WHOLE lot, but 1-2mpg is okay. I was thinking of adding a Comp Cam 212/218, but I want it to have more lope than the 114lsa. What do you guys about that same cam on a 112lsa? Should I keep the lift that comes with the 212/218, or would you guys recommend more/less lift with the 112lsa? I'm going to be upgrading my valve springs to the 918's and new pushrods, the usual stuff.

Also, would I be able to use my stock converter with this? I was wondering about this because I don't want to have to dish out everything all at once. I'm not looking for something to race, but want the power to be there whenever I need it.

Also, I will be purchasing some pacesetter longtubes to help it breathe. I will be having it dyno tuned for 93 octane What do you guys think?

 

it is a good cam, i have never heard of any that had it to report any kind of loss.
212/218 and the 216/220 may be on a stock LSA of 114 but they don't
sound stock.
most have stated that a TB stall works very well with the cams.
happy with the gains the cams produced, and i also don't recall any
stating a drop in mileage after installing the cam, you will need it tuned.

 

I have the same cam with the 115lsa. Not much lope but if you listen you can hear it. I have the stock stll right now. I can tell I need a little more. I'm planning on aYank TT2600 soon.

 

I think that would be a great cam.... 212/218 112lsa... should be a great little cam...

I used to have it on the 114lsa and loved it...

 

Thanks for the help guys. I just want something that's gonna give it more torque in the lower rpm and midrange. I don't ever get it above 4-5k rpm's, very rarely. I also like the lope because it simply sounds mean. You don't see a whole lot of Yukons/Tahoes with cams that sound like they'll take a bite out of your ***. I think that's the one I'ma get. What about the lift? Keep the lift the same as the 114lsa, just have it changed to 112lsa?

 

that is too much cam in a 5.3l tahoe with a small converter. that cam with a 2800 converter in a truck would be good IMO. I think you should look at a custom cam around the 210/214 range and maybe a 110 lsa. That will give you awesome torque and still pull to 6200 or so. ANd you will see power improvement accross the board.

 

The trailblazer ones on ebay are stalled around 2800 rpm's... Why exactly do you think a 212/218 is too big?

 

Cause I personally run a 208/220 on a 2800 stall and it is about perfect on low end and that is in a rcsb 2wd with 4.10's. It takes torque to move that heavy tahoe, which means more gas if your cam isnt going to pull untill higher in the rpms. That cam would be well suited if you were a rcsb truck and not a tahoe.

IMO I would not want that cam in my tahoe unless i was rnning 4.10's(atleast) and a yank tt3000 or similiar. You wont loose any towing capabilities with that setup. And when you punch it it will get you moving. But just IMO I think you could do better by getting a cam to provide more torque under the curve in your 5k+ pound suv.

 

ah, cool. Thanks! So you think a 210/216 would be okay just to squeeze a bit more out of the mid/top end? How's this cam profile sound...

210/216 .556/.561 110lsa

That cam with a trailblazer stall be okay? Let me know! I'm open to all suggestions!

 

That cam wtih a TB stall would work good. IMO. Also will sound good with that LSA. Now another thing to think about. If you wanted to run stock manifolds and stock intake, like im sure you probably want to you can go more indepth and look into a reverse split. Since your exhaust isnt flowing that great you could posibly switch that around go like a 218/214 or something and in some applications that provides good torque down low. Just depends on intake, heads, and exhaust. Which im guesing are close to all stock on your tahoe?

Oh and the 210/216 will not squeeze more out of the top end then the 212/218, its power will come in quicker.
