The first machine work for this 440 build

Those title weights are not accurate. That might be the weight of a generic Barracuda with absolute minimum options: slant 6, manual steering, 3 spd manual column shift, 7 1/4 rear, 9" drum manual brakes, bench seat, no radio, etc

My non A/C small block with aluminum: heads/intake/water pump, power steering, 727 Auto, 8 3/4, aluminum rims, manual disks, aluminum master cyl, on digital scales is 3209 pounds.
I'm sure it will be heavier than what the title says. I will compensate what I can where I can. I'll still be able to eat the lunch of many of the other cars on the road.
