Alright guys looking for some input. Been searching and searching the web for the best cam for my new build with not much luck. Here are the mods:

2007 GMC Sierra Denali

-L92 stroked to a 415ci
-L92 radial ported intake manifold
-102 TB
-100mm MAS
-5 inch CAI
-All forged internals
-Yella Terra Rockers
-Upgraded rods, springs
-Arp main and head studs
-10.5-1 compression
-Hand ported L92 heads
-LT 1 7/8 headers
-Dual 3 inch back through Xpipe, no cats, with cutouts also
-6l80 built trans
-3600 triple disk billet stall
-14 bolt upgraded locker with 4.10s (2wd)

Had a 227/239 .623 .613 115+3 in it when it was a 6.2 and loved it. Made 417hp/ 380tq with that setup.whatwill give me some big torque numbers from 4000-6500. Been having a hard time finding any combos in trucks with similar setup. Mostly street driving but don't mind a little bucking down low.

 

Get a custom one made to your set up so you can get the most out of it, i would go with either lil john motorsports or martin smallwood at smallwood race delilment i believe.

 

Do you plan to keep it strictly NA?

 

yeah for now. If i boost it I will change the cam to have the right setup.

 

I'd honestly keep the cam close to what you have if you're trying to maintain any sort of tq, especially with those L92 heads. In all honesty, run the old one in the new motor, you might be surprised what it does and not need anything different

 

I might do that. From all the researching seems that I don't really need to go with anymore duration.

 

Depends how aggressive you want it to sound and idle. You could add some duration and drop the lsa and play with advance to make it come in harder off the bottom.

Example. 230/244 114+3

That has almost the exact same IVC but a later EVC to help get the added air volume out. You will hear the added overlap. This is just an example.

 

I run the 239/254 .624/.595 113 +5 from BTR - they custom spec'd it 2 deg advanced from what their stage 3 400ci stroker cam is

I have 427ci and stock ls3 heads L92 intake but that is pretty close to your setup. running a 4l80e and my converter is pretty tight at 2200rpm and 3.73's right now (5.13's are in the mail as we speak).

I really like how it drives. It's a little pissy when it's cold(50deg or less ambient temp), but I let coolant temps get up to around 100deg and it drives great.

With that ported intake you could probably run it at +3 and see how it does. The 6L80 has better gearing in 1st so I bet it'd drive even better.

 

@ken 5.13s? Holy **** thats big
Are you lifted on bigger wheels or just like to party?

 

Always like to party my friend.

I had a D60 SF in the truck with 5.13's already but they don't offer the TrueTrac in that axle. Thing drives around great with that gearing. - Oh I run 37" tires so it's more equivalent to running between a 4.56 and 4.88's with stock size tires if you want to compare. I did the math one day to equate it to something.

I swapped in the 14 bolt and thought it had 4.10's but when I tuned for 4.10's the speedo was off, so sure enough I got under there and counted the driveshaft rotations and low and behold I have 3.73's

Great highway gear - I think I cruise at 1600rpms at 65mph lol
the 5.13's run around 2300rpm at 65rpm - so it's higher, just not screaming.
