Help build a 408 stock block 5.9!

I will have to see what my friend choses to do. At this point, it will be 408 cubes, TF 190 heads, and if normally aspirated i believe 11/1 compression using a cam similar to what i used in my 504 hp 408 build, a Comp mutha thumpr 235/249/107. That motor tolerated 10,50 compression with EQ iron heads and liked 30 degrees total timing. One thing i did for that combo was a true 4000 stall 10 inch converter, and 20 degrees initial timing , 30 total, coming in slowly by about 3800. With a 3.55 rear and 2.76 low it was a beast in a 65 Dart.
I suspect when the owner looks at the compromise need for boost, the choice may be no boost/ high compression. In Minnesota BP sells 93 octane premium, which gives us a bit of an edge over some areas.
