Low 12’s or not will be as much about “the car” as the motor.
Basic combo looks fine.
If the heads are “ootb”, a little clean up is worthwhile.
Don’t put too small of a cam in it.
Invest in a “good” converter.

Right now how is the distributor set up, initial , total timing at what rpm ? probably has the wrong pistons, like was mentioned earlier, what was the piston deck height >

Big motors solve a lot of problems. Go as big as you can in the 440 block. I would cam it so it is "on the cam" by 2400 to 2600, and use a well built converter that has stall specs similar to a 383 roadrunner converter. It should flash to 3000 to 3300 and respond like a stocker under normal driving. You and your dad will love it.

I went 540 in my motor, and having to go to external oiling and having the block clearance was a huge hassle, i think the 500" kit is the ticket for my dads car. what is a "well built" converter? I would change the cam to a good N/A set up with a 106 to 108 LSA (and degree it and change complete exhaust system with bigger primary pipes, 1 7/8 or 2.0 inch, with 3.5 collectors and a complete 3.0 system from the collectors back 383 motors don't have a long enough stroke to make much tire spinning happen with decent tires i think he just wants to go 500" motor.... i have been trying and trying to get him to let me swap his cam, but he would rather build a stroker.

what is a "well built" converter?
I will give you my opinion based on street use of the car: it is a converter that will allow you to flash to the RPM that puts the motor right at the start of the range where it's making good power. So if your combo is coming on strong at 3500 you'd normally want a converter that lets the motor spin up to that RPM right away, thus "flash". However, on the street it is no fun to just power through on the converter at each stop light, so you want that converter to be somewhat "tight enough" that it isn't flashing to that stall speed every time you apply the go-fast pedal, and instead does provide a decent amount of throttle response at the lower RPMs where most of your stop'n'go street traffic will be. To me that is what a "well built" converter is as far as a street vehicle is concerned.

What are the Schumacher headers? 1 5/8 inch tri ys?
Is the cam 274 advertised duration?
The lack of low end is the M1, 3.23s, and probably tuning. What is the compression ratio?
Now I need to pin those needles, got to feel that heat Hear my motor screamin while I'm tearin up the street

I dont understand this??
First 440 i put in my car, it was so simple
stock 440 shortblock, 906 heads bowl ported with direct connection templates Stock valvetrain, rockers and pushrods Direct connection .509 hyd cam Holley street dominator intake with 800 DP Pro parts headers YES the most "exotic " part a Dynamic 11" converter 3.90 geared 8 3/4 rear
At 3600lbs and regular pump gas, it ran 12.0's and IF you shifted it soon enough, and i mean soon like 5200 it would run 11.90s
a .073 jet in a cheater plate and it was a 10.70 car....
NO aftermarket heads, NO stroker crank, Nothing exotic.
I think people sometimes lose site of matching parts and with the aftermarket stuff that is availible..... With a 440 i dont see why its hard to go low 12's. Whats going to make or break your new 440 combo is the CAM and Converter. Dont skimp on those two things

so a 440 that will be a 30 over 500" kit with 9.6 to 1 compression, OOTB stealth heads, and if i can get to him upgrade the headers to some TTI's add a Comp Cam Xtreme Energy .545" cam, and maybe a 2800-3000 stall. with 3.55s or better. Sniper efi and hyperspark ignition and coil and distributor and a RPM intake?
This would be a good running motor that will burn tires and motive a heavy b body?
As far as riding in my a body 540, no he hasnt been in it. It hasnt run in years. Just rewired it and some other things, started it on Sunday for the first time in about a decade. The 1800 stall is killing you, I moved to one for about 3 days then immediately ripped it out for a 3500. My 500 inch stroker couldn't even do a burnout and it's a torque monster. With that said, it felt great on the highway with the 1800. Whats the plan for the car? 3.23 gears are pretty happy with the gear venders on the interstate. I cruise 85-90 all day long with that combo. My similar setup NA stroker in a 3300 pound E body went 11.7 in the quarter. I like the 3.23s + GV for highway cruising and happy to sacrifice the track time.

If it were me, I would change the converter to 10-11" 3000 stall and let it rip as is.
