  1. Hello everyone! Earlier this past week I received my stage 3 cam kit from Texas Speed, and long tube headers w/ catless Y pipe from Kooks, and sent my ECM out to HP Tuners for unlock. This thread will be a mini build thread of the process, and the results later this week after tuning is complete! Part List: - TSP L83TR-3 Camshaft [222/230, .635"/.635", 112 LSA, 32% fuel lobe] - TSP .660" Dual Valve Spring Kit - TSP DOD plug kit - New Pushrods - LS7 Lifters & new trays - Phaser lockout kit [required modification, TSP will be working on a new one based off of our measurements] - ARP bolts - Kooks Long Tubes 1 7/8ths" w/ cat-less race Y-pipe [3" to 3 1/2" collector] - HP Tuners ECM unlock & Custom tune So far, as expected, the block is still the same LT1/L86 as previous generation, however the new 6.2L L87 has a completely different Cam phaser, and the DOD delete plugs are held in by the OEM screws vs. rivet style. My truck currently has 19,XXX miles on it, and is looking to be in pretty good shape for the amount of on and off road abuse that I've subjected it to over the past year. As for the cam choice, yes it is a 5.3L cam, however I have no plans on swapping out the torque converter at this time, and I want to see where the limits of the new 10 speed are before I fully push the envelope. It will still offer a size able power bump in the 6.2L as I have the extra displacement, and after talking with Texas Speed, its the cam that we all agreed would be the best bet. To what I know, I'm the first 6.2L to get cammed, and so I have tried my best to document the entire process for anyone else that is looking to do the same with theirs, and as I found out in the process, the new L87s have a brand new cam phaser vs previous models. So, without further ado, lets get onto some pictures:
  2. What would be the best way to go about getting rid of all the clatter on cold startups on a 2008 Silverado 5.3L, and what would need to happen to get rid of the 4 cylinder mode all together?
  3. I have a 2005 GMC Sierra 5.3 and I tow a lot, sometimes daily. My mechanic is building me another 5.3 [i think it's a 2003 version] and am thinking about upgrading the cam. I've heard about the LS9 cam kit, but I wanted to see what you guys are running and how you like it. I am targeting around 375-400 hp on this one with just the cam kit, I already have a tune and true duals with Super 44s although I know I will need to re-tune for the cam. Don't want to have to change the torque converter as I have a brand new trans in it with converter, Corvette servo and shift kit already installed. Mine's a 4x4 and I run 295/70 mud tires on it. Not sure if that matters, but I thought I'd mention just in case. Also not planning in changing the stock exhaust manifolds out. So anyone been down this road here? Looking for cam kit suggestions....thanks for the help!
