440 Crank in a 383

It would a decent engine but you will just have a slightly smaller short deck 440, it would be a 440 with a 0.070" overbore. Even a 400 only gonna be a slightly bigger overbored short deck 440 with a 3.75" crank. I see no point stroking less than 3.91" for 400/440 and 4.25" for a 383 for 496.

I'd go stock 3.38" or just go with a 440 or if I was gonna go to the trouble of stroking the 383 at least go with 496.
You are right, a 440 would be a better deal overall. And the money spent on the 383 would definitely be more than the 440. Good points.

The only thing still going for the 383/400 will be a shorter deck and a bit better packaging as a result.
