Air/Fuel vs. Timing on stock ls1 with boost

[ddnspider]

How do you guys normally setup a boosted stock longblock ls1's? I currently have the car setup for ~11.2:1 A/F on 93 octane with 12 degree's of timing. I also have the IAT timing table pulling 1 degree with IAT's starting at 100*F and then 2* over 130*. It looks like the A/F is right on except the top of 4th it dips down to ~10.8. Just trying to setup the car for longevity. It runs awesome and pulls hard, no knock either. I'm just looking to make it last.

Little bit fat for my liking, I normally aim for around 11.8:1 at the engine pipe and even this can be a tad bit rich but very safe. If its stock and depending on boost you can run 14-15 deg timing. Ive had 10psi boost on higher timing with 98 octane here in AUS.

How long did the engine last like that? Everyone I've seen said they set it 11.2-11.5 and keep the timing safe.

11.8 is only marginally past 11.5 so it is fine (if the IFR/VE/MAF are correct (or correctly scaled))...

he's done many of them.
