FYI
the OP's cam installed at 103(split-overlap), looks like;
279intake/117.5comp/101Power/296Exhaust/73.5 overlap/Ica of 62.5
Whereas the 292/108 in at 106* looks like;
292 intake/108 Comp/104 Power/292 exhaust/76* overlap/Ica of 72
These two engines will have completely different personalities. and that's before you even look at the .050 numbers....................Jus saying.
-----------------------------------------
Given two identical 360 engines, at the same 10.7 Scr :
the Comp cammed engine might pump 164psi, whereas the
292/108 cammed engine might pump 147psi. whereas the
292 in my 367HO, in at 104, pumped ~177psi, @11.3Scr
But OPs engine with open chamber heads is not likely to to be a 10.7 engine. Perhaps 9.5 at best, which would put the pressure closer to 153psi
-------------------------------------------
BTW;
I ran that 292/108 in my 367/4speed/DD, for just under one year. I ran it from 100 installed to 108; in 4* increments. I tried really hard to love it. But it did not repay me. It hated 3.55s : top of First gear was 61mph, Second gear was 88mph, Third was 116. Cruising: 65 was a tic under 2900. So, I yanked it.
The next cam, with no other changes pumped 195psi. Now, that was really something! I was really impressed by the bottom end, but the top end was a lot softer than it had been with the 292. I retarded that cam, got 187psi, and the top end became acceptable.
Then I threw in the towel, got me an overdrive and 4.30 gears; and finally, all was well in the world; top of Second was 70/64 in First-over, and 65= 2700
I have never missed that 292 cam. Plus it sucked gas big time.
I was very sad when this little 270/110 cam dropped lobes.

IMO
Some people say cylinder pressure is not important. I say
That's like having a wife, who has no interest in sex.
In both cases, all the parts are there, but they ain't put together right, and neither is a keeper.
That's my opinion.
