Starting Shift Point

My 360 has a 750 vacuum Holley, Torker II, 11.25:1, ported 915 heads w/ 2.02 intakes, 292-.508 purple cam, 1 3/4 headers, stock rods and crank.
I bought it with all of this and have disassembled it to verify everything. I can’t speak to the quality of the port work. I don’t know who did it, and I don’t have any experience with port work.
Anywho, what’s a good shift point to start out at?
