So I decided to build a 360 for my Valiant :)

I have a combo nearly exactly as you are contemplating including a 230/237/110 cam.

Mine is currently at 11.1 Scr and under alloy heads. It runs on 87E10 just fine, even at 185psi.
What I'd like to tell you is that the previous cam was 223/230/110, running at 11.3Scr and close to 200psi; which, had waaaaaay more bottom-end torque, but still went 106 in the quarter, on it's only one run ever, at 3650 pounds and 750ft elevation.. with 3.55s and 245/60-14 street tires.

After that cam lost lobes, I went to the next bigger.
I had to add 16% more low-gear to get the torque back. If yur gunna run 4.10s, I suggest an overdrive, lol.
If yur NOT gunna run the pressure up, I see very little advantage to running alloys on the street.
I ran that 200psi still on 87E10, still at 34*@3400rpm, still with 3.55s, still at 3650 pounds, and for 4 years.
But I won't tell you that I once got 32 mpgs with that smaller cam, allbeit geared 65=1850, cuz then, all the naysayers come down on me.

If you are at elevation,
there are a couple of FABO guys in Colorado, at elevation, that were rather shocked at the powerloss at 5000ft. Maybe they'll chime in.
If you don't want to be like them, you'll need a special build to compensate for that.
I highly recommend you chose your cam first, then design your build AND COMBO, around the cam.
And I highly recommend a smaller than 231/110 cam.
And if it was me, I'd go to a 107ish LSA, to get some overlap on the smaller cam. But, you just gotta keep the pressure up;
