How Much Frame Notch to Fit 15x10’s?

That is tough, that could possibly clear with out notching. But for notching you want to notch the frame back until it is even with the inner wheel wells. Going deeper won't help because the inner wheel well is in the way. We the UMI kit we run a 11" wheel and 315 tire on a 79.
Unless you are going to move the wheel tub inward too. Best to do it once and do it right. When we did the wagon we installed all new inner tubs despite only notching to the seam on the frame. All that to say the issue isn't the width of your wheel it is the section width of your tires once mounted; not to mention the backspacing of your wheels, the diameter of your tires, and vehicle ride height. So, if you are at stock ride height, with 26" tall tires, and a reasonable offset it isn't going to matter as much as being slammed, on 30" tall tires, with lots of negative offset.
There isn't a one size fits all answer to this, just a lot of rule of thumb.
I would notch the frame so it is flush with the inner wheel tub and from there I would do some mock ups to see what you can actually fit before ordering rims.
With a 2" drop on a 15 x 10 with the right backspace might fit but I feel a smaller tire would be needed to provide enough clearance.
I am not sure who's tire you are looking at in a 315/55R15 but it will have approx 13" of section width and that will be the issue.

I wouldn’t notch past the inner tub unless you are going to widen the wheel tubs. My notch is to the edge of the spring bucket with tubs widened 2.5”. 15x10 welds 5.5bs with 295 55 15 MT dr’s, 2” UMI rear drop springs and modified fender lips. Car sits just on top the tire. Notch is wide enough to fit 325 50 15 dr’s on same rim with 3/4” clearance to frame. Not sure the 325 will tuck in fenders with the 5.5 bs. This is on a Cutlass, hope this helps out.
Sorry, I meant 295/55/15. Should be 0.8” wider section width than the 275’s I have now.
That helps a lot. I meant to say I will be running 295/55/15 m/t drs. Running the 275’s now. It sounds like your car sits like mine.
Your 275/60's on your 8" rims should have a section width of 11.1" the 295/55 should be at 12.1 on a 10" rims but should still have no problem fitting .
I have M/T 295/55 on a 9.5" rim with plenty of frame room and the tires are tucked in even the section width doesn't stick out and I also ran M/T 295/65 but decided they were too tall.
