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
