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:

I did not manage to get a baseline, but will be providing crank estimates, and eventually get it on a local dyno for final numbers. 

Would have been good to see some before/after numbers but will be a great build nonetheless bud.  I'm sure others have dyno'ed theirs in the past so you should be able to use those numbers as a rough base. 

 

Good luck on this one!

Will have to upload in separate posts as the video files are too big. Tuning was a bit of a hassle with the new ECMs as the VE Tables are all AI controlled. Even tuners that know what they're doing will take some time to figure out the work around, and to adjust everything to where the AI can make sense of it all and learn. We have everything dialed in right now, just bumping the power limits up until it stops cutting under WOT. But as of right now we're showing over 600 ft-lbs at the crank and the computer is holding back. If all goes well we will have full power by tomorrow and then I will be scheduling power pulls at a local dyno next week for final numbers at the tire.
