What should I expect from 450hp?

"Small cam" yes of course,
but as @Oldmanmopar said; "Too big of a cam for that low compression",
And I add;
1) especially for a 3.23 geared, manual-trans streeter, which will likely spend the vast majority of it's life below 4000rpm,which is
~37mph in first/52 in second/71 in third/100 in direct.
Typically, I shift my 180psi 367 at 2800. That is more than enough to work traffic. And to accelerate briskly to 65mph, 4000 is way more than enough.
2) especially for aluminum heads which will easily accept 185 to 195psi cylinder pressure. Which at Part Throttle, that high pressure is simply amazing. Putting alloy heads on a 135psi stroker, IMO, somebody goofed; those heads will never reach their potential.

At a measly 7.3/1 expansion ratio, 135psi makes 986 psi in the chamber at WOT, at peak torque.
At 8.8, 175 makes 1540psi.
The latter is~ about 56% greater.In a streeter, I know which one I want.

I'll give up 3 cam sizes for that latter. Oh wait, I already did.....
I will never ever go back to low-pressure, not with any engine in any car, and I don't care how many more than 3 speeds it has,lol. For as long as we can still buy at least 87 gas, I will continue to run 180/185psi, with alloy heads.
If I knew what @yellow rose knows, I would try a hi-pressure iron-headed beastie.
While I would tend to agree with a dcr under 8:1 being a turd at low rpm you made a huge assumption on Intake closing degree not knowing the actual spec. That could be the difference between a 7.2 and an 8
