Ignition timing

Building a 440 using TrickFlow heads, 78cc chambers, 240cc intake runners.
Comp ratio will be 10.5:1, pump fuel.
Solid roller cam.
Street driven.

Wondering about total timing. Has anybody built a similar combo?

Close to mine , very close . 23 initial , 34 total/in a t 3000 , 93 pump gas .
