I have a guy that is going to be taking out his Comp 222/224/112 cam because it doesn't work with his supercharger! And he also has a Yank 3K stall he is taking also. He is selling them for $600 is that a good deal? ALSO is that a good cam for my truck? He said it changed the idle a little bit!!

 

Definitely too big for your truck.

 

His truck is just like mine! 6 lift, 20's, 35's 2006 5.3

 

With your truck the biggest I'd go is 216/218 or if your wanting to save money find a nice 02+ Z06 cam someone has laying around. My 01 on 37s had an 02 Z06 cam and I loved it...

Z06 cam specs: 204/218 @ .050" .550/.550 on a 117.5 LSA P/N: 12565308

 

Stock cam! I don't care what anybody says everything you gain on the top your gonna lose on the bottem. If you cam it up you gonna lose lowend, and unless you have swapped gears for that rig your gonna need all the low end you can get to plow through the mud, and get if off quick. I would spend the money on a stall, somewhere in the 3000 range. I gained almost a full sec from my Yank. With your combo your gonna be hard pressed to get those kinda gains from a cam.

 

You tell him to keep the stock camshaft but then spend money on a torque converter with 1000 rpms higher stall speed than stock? Do you ever expect those tires to move??? This is terrible thinking for a tall lifted daily driver.


If anything you want to go with in the other direction. I just ordered a new torque converter for my 5.7L/4L60E/35" tire truck. It's an OEM replacement converter refurbished with a new set of internals that brings the stall speed down, to probably 1750-1800 the salesman said. It's a heavy duty unit meant for a Silverado 1500HD. He said it will lock up quicker than stock giving me 100% power right when I really need it to get the heavy 35's turning and offer a lower lock up speed on the highway helping out with fuel efficiency.

And I agree with the guys above. Anything in the 215+ duration range is too big for a lifted truck. You can only get away with so much lift and duration before you have to make sacrifices at the low end for top end gain, but you'll never gain up top what you lose at the bottom. The camshaft in my 5.7L is a 206/212 by CompCams and it's an absolute torque monster. Sure it doesn't pull past 6200 rpms, so what! That's not what you do with tall tires, especially if you're not geared for it. Look into the XR259 from CompCams. Best $350 spent on a lifted truck camshaft.

 

I thought the stall with no cam was wrong! i have been looking at those xr259. is that what you have?

 

Why wouldn't you, Torque Converters mulitiple torque, not diminish it. It would allow the engine to get up in the Rpm from low speed and transfer more torque to the wheels. As we all know torque is what moves a vehicle. If you buy a good converter, like a yank it can be setup tight like mine and won't feel sloppy like old school converters. It's gonna be more noticeable on a big tired truck, but thats why I wouldn't recommend a 3600. But if you want performance it's bar none the best way to go. If you have no stall speed and make less torque down low (with an aftermarket cam) the truck is gonna be a pig.

 

Not necessarily a high lock-up verter will transfer the torque to the wheels much faster, i.e. no hessitation which is what you would want with a lifted truck. A stall creates a "flash" of torque after it stalls up in the rpms which if your pullin 35" tires is not always a good thing. yes I know a stall would help in acceleration but most lifted trucks prefer high lock-up verters, sometimes w/ a mild stall, like a 2400. if someone needs more lowend in a lifted truck they need to just gear down, since they're not meant to go over 100mph (at least not safe at 100 )

 

I totally agree.
I don't know what this salesmen is telling you but, last I checked you PCM tell's your converter to lockup by activating the TCCS. The converter doesn't just magicly lock up. If you have a tuner you can lock up your converter at anyspeed you want. A heavier duty converter is going to have more holding power not lock up any sooner. A lower stall speed is going to make it slower, adding a oversized cam is gonna make it slower. If those are his goals then I'll step back and give you the lead on this one.
