How about the CompCams XR265 for the 4.8L? I know that thing makes some decent high end horsepower so utilizing the upper 2/3rds of the rev range from 2000-6000 would make for a fun ride. It's a 212/218 .522/.529 on a 114 LSA. Power would really start to come on around 1400 rpm's and pull hard to beyond red line if you let it. In a 4.8L it really is a 1400-7000 rpm camshaft.

By the way that cam you selected, LS1nut377, is a 2800-8640 camshaft.
You are a rare breed sir. My personal suggestion, stick true to your opinions and even though most on here will bash you for holding firm on a small camshaft just hunker down and take the abuse. There's perhaps 3 of us now who know that camshafts aren't wiggle sticks to be turned at such a high RPM where a Genie comes out to grant unlimited horsepower. That 210/218 cam you've hinted at will most likely make a torque monster out of your 6.0L, so good choice. Just depends on how aggressive the lobes are and the separation angle.

 

Thanks for the kind words. The cam is the Vinci 062

210/218 .551/.551 112 LSA 52* overlap

I just want a ton of torque and throttle response down low because that's where I drive. And I think that cam will still have a better top end than stock if I do decide to go WOT. I plan on using a trailblazer stall and adding 4.10 gears (from 3.42)

 

Perfect cam ya got there. Good find, it'll definitely get the job done.

 

id go with the comp 212 218 in a 4.8..even then it still needs a stall converter to work nicely with it

 

well thanks for all the imput ill take it all to the drawing board real soon, but i gota tell ya i love those high rpm's i shift at 7700 in my t/a pulls all the way to it!

 

the truck intakes suck at high rpms..usually top out around 6300-6500 rpm..besides the heads will not flow what that cam can put out..buy a fast intake and some heads and shift it at 8k

 

ah ha so i shall!!!

 

so do it already..add some juice to it while your at it

 

I put a 537 in my 4.8 and thats about all you want! took almost 8 hours of dyno tuning and hptune to get straight. I LOVE IT
