they said they are talking to ARP right now trying to get something going with them

 

Thats the truth!

 

I have had alot of people tell me, that you are like the head "CAM" guru around these parts BigTex, whats your take on what I might need?

 

Since I now have a radix, 6L and aftermarket cam, I was holding back until I had a good grip on what the radix needs before posting. I've got a couple of thoughts, but wanted some hard facts before throwing them out.

Do you plan on tuning it yourself, mailorder, or dyno tune? Will you install headers? Any other major mods you plan on doing in the next year or so?

 

Come on grippy, can you type any slower.....

 

Current Set-Up 2500HD (5400lbs), 6.0L, 4l80e(stock torque converter that stalls at 2500rpm), MagnaCharger Radix Kit, Magnaflow Cat-Back (exhaust is dual 3" into a dual 3" INLET, single 4" OUTLET out the back). 32" wheel/tire combo, stock 4.10's (G80)

Planned Mods: Custom and/or Dyno Tune, I will also be purchasing HPTuners or EFI Live, Mid Length Headers, Cam/Springs/Roller Rocker, E-fans.

Thats about it

 

Thats about what I'd expect you to have / get. I was really curious to know if you were going to get headers. Are the dynatech's carb legal in CA? You probably can use the added flow of their front pipes. A potiential issue you will have will be the catalytic converters melting. Since my aluminum gasket recently melted, I know that the FI setup is creating much higher exhuast temps. One SS guy recently had one cat melt / clog up and caused engine damage. Soooo..., I'm wondering if the dynatechs cats will withstand the heat more, or if they can be bought with a better converter.

All that being said, exhaust flow is a big consideration in your cam choice. Along with that - what rpm do you want to spin to / shift at? The rpm powerband of a camshaft is directly related the the durations. You don't want to get a cam thats making power well past your shift points. That means you'd be giving up some lower end power for no reason.

If you want to get the best fit in a cam, make the cam your last mod. Then you know whats in your truck and what it needs, not just what you'd like in your truck.

 

Posting my thoughts on this lingenfelter cam....

Look at Lingenfelters market - high end vehicles. Not only high end vehicles, but vehicles that should run stong, yet idle like stock, have no drivability issues, hold up nearly as long as stock, pass emissions w/o issue, and have very few warranty claims. Those goals for a vehicle mean you make power sacrifices, just like GM does from the factory. Passing emissions, long life span, no tuning problems, perfect idle, etc... these are usually directly in contrast to making peak power. I think that lingenfelter cam will make more power than stock (just like the LS6 cam would), but there is more power to be had.

 

Dynatechs are not Smog legal unfortunetly. They are smog compatable; one thing nice about them is they are a bolt on affair with the Cat/Pipes and Stainless Steel which is tempting. My main interest has been TOG's due to CARB. At the very worst I will be getting the HD TOG's with 3" collectors.
But then again, I haven't been able to reach them for awhile.
Not sure if I'd be comfortable shifting at 6500. More likely 6000 with a little over-rev protection (i.e. room for error) available.

My biggest thing is, low end grunt, I really don't need anymore and don't want to lose any. Although, with a low (6k) shiftpoint who knows.

 

I'd think it would be to your benefit to go with something shorter and that releases gases as fast as possible.

Big tube, short design like the LaPoles. Under $600, mid-lengths.
