Need HELP choosing cam for a 6.2l l9h sierra denali please🙏 2012 Sierra Denali 1500 -6.2l -L9h -AWD (borg warner transfer case -3.42 gear ratio Current Mods -speed engineering LT headers, true dual, catless -volant cold air -91 octane -efi live tune I will be getting stock heads cnc ported/polished from GPI watney and also doing trunions, lifters, pushrods, springs, retainers, dampeners, and basically beefing up the internals to go boost later and because truck just hit 140,000 kms and want to do preemptive maintenance. Also most likely a upgraded tranny cooler and oil pump and thermostat as well. Im keeping VVT I was looking at the GPI LLT2 VVT truck cam and also the TEXAS SPEED Stage 2 VVT truck cam (maybe a custom grind? ) TSP 220/232 .600"/.600" 113 LS 1400 to 6400rpm (Suggests dual .660 springs and 2800+ stall ) GPI 21x/23x .55x/.55x 113+8 2250 rpm and up (Suggest ls6 beehive springs and maybe a stall but not necessary) If stall is gonna help me or is neccessary obviously i will get a circle D or something. What would be the best of the 2? I know it will be splitting hairs at this point but Is the TSP gonna be harder on the valve train than the GPI or does that even matter after i beef everything up. Ive been through the https://www.onallcylinders.com/2019/03/14/l9h-6-2l-engine-upgrade-guide-expert-advice-l9h-mods-maximize-performance/ Which One do you think would post the best results in torque and hp accross the entire powerband? I want to keep my low end obviously as much as possible as it is a daily drive but will be a bit of recreational track fun as well.and i do alot of highway driving and hit speeds up to 200kms hr quite sometimes on track or stretches of highway. Im quite entry level when it comes to all of this just basic entry level research. thanks Mack Edit Quote Multi Subscribed Reply to Thread |
I've used the TSP cam on a couple Fbody 6.2 projects. Ran great. 3000 stall converter. Ran great and easy to tune. |

Which cam would u go with if u had to pick based off lift duration and LSA and all that? 210/230 .550/.550 113+8 220/232 .600/.600, 113 LSA Looking like the top one from GPI might be better low end torque? |
This should be in Gen IV Internal. |
