I'm honestly not sure, but there are many aftermarket CNC'd options available. I got my CNC'd StageII 317's from WCCH (a sponsor here, there's a link to the right>>>). I haven't run them yet, but there are flow numbers on their website, or you could give Richard at WCCH a call to discuss your options. He is awesome to talk to and just about the most knowledgeable GENIII engine guy that I've ever talked to

 

hmm custom grind cam. Well then what kinda specs do you suggest?

 

Given your requirements, I'd go with the EPS 234/246 .602/.607 111 lsa

 

are u suggesting those specs to me gmc?

 

yes, I took into account your setup, and my experience with their smaller cam in a 6.0.

 

hm, wouldn't that be a little too much cam for my usage? my truck will see the street more than track. I only go to the track like every other week. but i wont lie. i run it every friday and saturday night whether i'm on the black top or not.

 

if its not a daily... and you dont care about gas mileage.. i would go big... put a hell of a gear, hell of a stall and do something in the 230 range.. dont go too big... but dont go 218 either

 

fred. i noticed you have a 2001 with a 6.0 and it has the cam i have been looking into (224/228). how do you like the way it runs? and wat are you trapping in the quarter?

 

i sold it before i ever ran it... but the guy i sold it to is going to run it next wed at a test and tune night... so ask me next week... but i loved it, i thought it was a perfect balance of torque and HP... for a heavy truck it pulled like a ****... ill let you know what it traps.. im guessing a 12.9 at 103-4
