Should I go Big block or Small block?

I have a completely rebuilt 440 that is very streetable I am looking to sell. Everything in it is new (e.g. Pistons, Cam, Lifters, Push Rods, Bolts, Rockers & Shafts, Valves & Springs, Oil Pump, Bearing, Distributor, Timing Chain) or reconditioned (e.g. Rods, Crank, Heads, Etc.). The heads have been port matched to the intake. I am looking to get $4,600 for it.
