Need some advice on choosing an engine
I don't know why the 383/3.75 ain't a more popular package. When done you got a slightly smaller bore and cid than a 440 but it's smaller dimension and lighter internally and externally with parts nobody wants.
If you think of a 383 in small block terms. Like is someone made a heavy duty 225 lbs 4.250" bore, deep skirt block that could high hp loads, and tall deck so it could be stroked to 500 cid people would be tripping over themselves to buy one for thousands of $$$$. But call it a 383 big block nobody wants one lol.
That's what we are doing with a 383. 4.25 x 3.375 to 4.28 x 3.75. 431CI result
Builder thought he had 440 but it was 383. Great shape. So I said heck, let's see what we can do. Should spin up to 7k+ like SB but with decent low end torque.

Magnumforce front end kit. So gone with torsion bars. Customer headers (No choice like B3 says. Tight!) should be built this upcoming week.
Not cheap. But not crazy either. Built/designed for strip but to also survive Drag Week.
We should see in couple weeks what the dyno says.
