Very efficient chambers have no need for a lot of timing.
Speedtigger has/had a combo close to yours and right near 30*, My combo is similar but with LS3 heads cut .050 for approx. 10.5:1 running 93 pump **** and 32-34* flat-lined from 1000 to 8000 (7500rpm limiter).
As above, good read

I run a similar combo. I played with map for a while and eventually decided my motor didnt need it. Im around 12* at zero rpm ramped to 31* at 500 rpm flatlined through the rest of the graph. Mine seems to idle, cruise and WOT best at 31*
Every time i tried something fancy it would act up.
