Thanks, sorry, bad example I guess.. I couldn't remember the specs except he had like 3 or 4 of them just alike with 337 manifolds.
I remember having -1's on a 10.5: 440 and of course it felt a little soft (compared to say a 440 magnum) until around 3200 and then LIGHT SWITCH big power....which was fine for the way I drove it. When I did the 517 with the Chapman Max Wedges I was very very surprised just how tractible and FAST the motor revs and pulls, more like a Hemi than a wedge which I really like...a hemi with 91 more cubic inches of trorque at any RPM though. As much torque as this thing has I can only imagine it with a 25 degree smaller cam in it, I'm at 11.5:1 though so I couldn't go that low on degrees. But nonetheless, it revs like a Comp eliminator motor and I run 3.54's as well. I run a 4000 stall 9.5 but I have no doubt this would pull great with a 2800 converter too, the torque is just so broad and there at any RPM. not a thing soggy or sluggish about the
throttle response:

It made 545/545 or right around there but it is ALL DONE at 5300, massive torque (runs 12 teens....and aero challenged no doubt in a 3800 pound jeep CJ-7) .
https://www.youtube.com/watch?v=7bNsxJLSie0This was basically the same recipie I used for my 427" Stroker SBF Cobra replica and also the 440" W2 small block Hollis and me did a couple years back. Big difference though are the ford and mopar Heads are a bit better...so more RPM cieling.
In a jeep that's awesome but In a charger R/T clone, well, I'd just want a motor that revs to 5800-6000 at least, with a tractible, linear power curve that feels great behind the wheel. Whether I go up there or not.
What I was saying (kidding of course) about turning it into a 455 OLDs is a motor that a motor that is ALL TORQUE is almost always hair-triggered and a tire shredder which is great if it hooks....but still it's all done at ~5000RPM and then the power drops like a stone, I guess a Harley V twin is another good analogy. you get really chugging and then....you're looking for a place to drop another quarter in the slot to keep the ride going.
Max Wedge ports are bigger (still smallish compared to most BBC and NASCAR FORD stuff) but at 500" they're just not too big, I generally like to run as large and free flowing an intake port as I can get (and afford, lol) ....up until it starts to kill torque at the lower range if whatever me target RPM may be. I can then "tune" the powerband with the cam and gearing. It's just a philosophy, not really applicable to drag racing but more like a road race type powerband, for a dual purpose car.
I thought (still do but opinions Vary) that -1's with that mild cam combined with a single plane (works better with fuel injection...hands down) would give him just about close to perfect at any RPM. 496 from a 440 = thats 56 cubes = another whole cylinder's worth of displacement at any RPM, and all stroke too.
I respectfully agree though, we each have our own idea of the ideal recipie,
