By the way I showed the machanic these pages and he still argues the differances are so minute there basically the same. Told me I could buy a chip and run with the best of em for thousands less. But I think I ll do my exhaust and start from there.
"Got the chip" I think it made a difference. Certainly was a lot more affordable.
ask the mechanic what he meant about the timing, other than that he sounds correct. Maybe you misunderstood the timing answer ... I think the oil porting was a little better on the 2002 - 2004 years.
a Lot better.
Early LS1 blocks vs 2002-2004 LS6 blocks had very different oiling galleys
late 2003 all LS1 were changed to LS6 block.
part of that challenge may have been most F body guys call ALL LS6s LS1s

I tried a few affordable choices myself......
1) Flux Capicitor
2) Chip
3) Di Lithium Crystals
I think the Di Lithium Crystals made the biggest difference. As long as the Crystals don't overheat, I gain like warp speed in the seat of my pant's..... LMAO
