Ballpark estimate for the cost to do a 5.7 Hemi swap in a '70 Charger

How much would it cost to rebuild and upgrade that 383?

The 383 of mine has been rebuilt. I built it in 2020 but in the 4 years since I've had it running, I have less than 300 miles on it.
I do have a 440 crank that I could use, that would increase the stroke and get me to around 432 cubes. I like the idea of having an overdrive transmission though and with a big block, the options are limited.

5.7 with a 392 cam and I little gear is a good option.
