This truck got dropped off almost exactly this same time last Sunday with a bad motor. We found 2 bad lifters that ate the cam lobes, a bent pushrod and 2 intake valves that weren't sealing and failing a leakdown.
We did a full rebuild with tsp stg 1 cam, dod delete, new oil pump, cam,main ,rod bearings and new rings Along with a valve job.
Also got longtube headers and y pipe when she went back together.
1 week turnaround damn near to the minute. All in house.
Not too shabby for 2 guys with newborn babies at home... lol

In 20+ years of tuning ls motors i have never put this much timing in any ls on 93 octane even na. This damn little sissy low compression motor with a 0 overlap cam wants ALL the timing!
I started low @ 16* and got all the fuel dialed in perfect @ 11.7 afr.
It made 530whp. I started bumping 2* at a time and it kept jumping 20+ hp each time. Last night I just called it good @26* made 623.

Come out today and decided to pull it in 4th on the dyno after getting my rpm hookup fixed so I could read tq.
Made 644hp/560tq.
Checked the plug and it STILL wanted more... put another 2* timing in it and bam! Another 20+hp/tq jump. This re****ed (literally) damn motor has 28* timing in it on 93 octane with a 2.9 whipple on 9lbs of boost.... I put 30 in it just to see and it only picked up 5hp and 7tq. Back to 28. Which is still crazy.
This is the graph from 26* to 28* back to back.. final was 667hp 586tq.
Not bad from the 530 it started out with

Stock ls3 truck heads
Stock ls3 camaro manifolds
2.5" exhuast
2.9l whipple 4.0" pulley (8-10psi)

Now time to take some timing out and put it on some 87 octane and cruise the country!
