318 bogging at high rpm, but only in first gear?

You should only NEED that kind of idle timing if you don’t have enough compression or your cam is too big or you don’t have enough compression.

Very rare that I build something needing that kind of idle timing.

I just did a street BBC that made 640ish HP at about 10.25:1 and all it would take was 20 initial. It might take that or a skosh more in the car, depending on his converter.

His cam was 250/254 at .050 which is less cam than I use.

I’m not saying everyone builds their stuff wrong but when you see initial timing like that we can say they missed somewhere.

Or they have a weird combo.
