Was in the 5.3L. I'll have to get home to get all the specs firmed up. Custom ground by Cam Motion. Later failed and the reason I now have a 6.0L. 205/212 .550?/.600? 114LSA +4 advance.

 

Ok how about I ask this.. IF I don't want to degree the cam and install it straigh up, can I spin the stock lq4 with gt2-3 cam and yellow ls6 springs up to 6300 or where ever the cam stops making power?

 

im shifting mine at 6500 thru all gears and should have went to 68 or 7000 cause it's still pulling like a ****

 

The fastest Silverado SSS with a Radix used a cam bigger than that and shifted somewhere around 6k. I doubt you're going to get much more torque by advancing the cam and if you do it'll be in the power range where you don't need it. The weight may sound like a big deal, but alot of the trucks on here are around the 5500lb range and more. If you watch your truck when you're wide open you spend very little time below 3k (especially with a Radix) and that is where advancing the cam is going to help. Above 3k I doubt you'd see any gain on the dyno or at the track by advancing it. Like Brian said, with a supercharger (Radix) you don't need any more. I fully agree with him on that.

 

Especially with 4.10's I can see that. I've yet to drive the truck with the radix so I can only compare wot stock which spends some time below 3k because it jsut bogs. Do I need rod bolts to spin above the stock rev limiter of 5800

 

**** I hope not, I spin mine to 6100 daily. i think you will be fine to around 6300. Above that with the boost and power, at least IMO I wouldnt chance it, but thats me.....
