What should I expect from 450hp?

OP gave us all the info we need, namely 235* cam and 9.5Scr. I wikied the elevation, and got 1900ft.
The advertised on a FTH [email protected] cam is gonna fall into a very small slot of plus/minus 2 or 3 degrees, say ramps of 42 to 47 degrees. This makes the 235 to be about 277 to 282. I chose a 284, cuz that's a typical off-the-shelf cam in this range.
I installed it at 110, which takes the guess-work out of the LSA. That makes the Ica to be
180less {[(284/2)-110]+360}-284=72*....... At whatever, tappet-lift. Could be .008 with a Mopar/ Engle/ Hughes; or could be .006 with others. No big deal, to prove my point.
The next smaller cam will only change the Ica ~3.5*, and maybe 5 to 7psi, so not enough to create a big change in proving my point.
I hope this clarifies my post

Here is the same engine with an Ica of 69*
Static compression ratio of 9.5:1.
Ica of 69*, 1900ft elevation
Effective stroke is 3.01 inches.
Your dynamic compression ratio is 7.40:1 .
Your dynamic cranking pressure is 137.68 PSI.
V/P (Volume to Pressure Index) is 126

And at what it needs with that 235*/284cam
Static compression ratio of 11.5:1.
Ica of 69*/1900ft
Effective stroke is 3.01 inches.
Your dynamic compression ratio is 8.90:1 .
Your dynamic cranking pressure is 177.54 PSI.
V/P (Volume to Pressure Index) is 163
And for Ica of 72*
Static compression ratio of 11.85:1.
Ica of 72/1900ft
Effective stroke is 2.92 inches.
Your dynamic compression ratio is 8.92:1 .
Your dynamic cranking pressure is 178.08 PSI.
V/P (Volume to Pressure Index) is 158

yes you could run it at 8.0ish Dcr, like this;
Static compression ratio of 10.6:1.
Ica of 72*/1900ft
Effective stroke is 2.92 inches.
Your dynamic compression ratio is 8.01:1 .
Your dynamic cranking pressure is 153.70 PSI.
V/P (Volume to Pressure Index) is 137
But note that the VP is again feeble compared to what it could be. You could run this in a drag car no problem, cuz VP means nothing in racing. But on the street, Feeble VP shows up as a soft take-off. I get that the OP doesn't speak of a weak take off, and may already have found his problem with the not-audibly-complaining BFGs. But after he fixes that, VP is gonna become important. Well, with a stroker, maybe not.
But crickey, you can run 155psi on iron heads, and not have sprung for the alloys.
