I’d stick with something around 212/218 112lsa and a 2600 stall to keep the torque down low.
When I put my 218/226 114lsa in my with a 2600 stall it felt like CRAP. A tighter lsa would have help a little..The absence of low end torque in a heavy full-size truck feels miserable imo. Don’t let tsp oversell you like they did to me.

Ok well im not worried about being oversold from tsp due to the fact that all the cams cost the same price no matter the size same on the converters that i am interested in. What lacked the most on your cam? Low end? Did you dyno it? And yes i didnt have blackbear delete the afm but i will this tune and im going to go ahead and install the delete kit cause i do have a lifter tick right now so hopfully that will fix that.

No low end, worse than stock even, and crappy mid range with a 2600 stall. 300whp
I mean oversold as far as pushing towards a cam where you’ll be forced to purchase more topend components in order to run the cam and a new stall as well. Don’t get me wrong, a 3000 stall is a great way to get these whales out of their own way.
Just consider how much power you want to make, and if you’re going to make it during an RPM range you that accommodates you’re driving. Usually lower range with a big heavy truck. Then, will your trans and driveline support the powe? I’m on a 33” OffRoad tire so I also had to consider there will be more stress on everything in my situation.

Mconcha, in your situation what would have helped you get more low end? Say someone went with somthing crazy big say 233/239 or 235/240 how do you get back that low end loss. Saying your tranny and rear end can handle everything. Also Im putting 33s on 24s on my truck with a less aggressive all terrian tire. Im thinking of going with 4.3 gears. What gears did u run?

I have to agree with what was stated earlier. Sell your current truck and start with one better suited for upgrades. I found a flex fuel 2010 LMG 5.3 with a 6l80 and I can't even begin to calculate how much money that alone saved me. If I had gone 6.2 I'd be even better bc of more cubes obviously but no dod or amf to deal with and that not a cheap fix. That particular year isn't well equipped for added power with out a lot of modifications. There are better choices that allow you to spend money more effectively...

Thanks for the input and i have taken that into very serious consideration... so i guess my biggest obsticle to caviet off of that is what would my best setup be to keep factory rear end with updated gears...has leveling kit with 33s on 24s... and also get the most life from the factory tranny... with or without new converter. Im guessing i would be looking in the $2500 range.

Smokin. My truck is a 5.3 flex fuel lmg. Are you saying to sell it and go to a bigger motor? And yes i am going to put a trans cooler on it. Im trying to get out of my own way here as i know bigger is not better. So if i went with a 3000 stall what would be a good cam size that would help in the low end with minimal loss?

I have 3:73 gears, 4:10+ would be a huge help. As well as a larger 3000+ stall. But I didn’t want to go with steeper gears or larger stall because I put a lot of miles on that truck and wanted the drivability to be as close to stock as possible.
