Resale Value - LS vs SBC

[MDPotter]

Not trying to open the LS vs SBC debate here, just looking for feedback in terms of resale value of a completed restoration, whether it be LS vs SBC.

We bought the truck with the intent of restoring it and selling it. We're not in this to make money, it's just a hobby, but we don't want to lose money when we finish it and sell it either.

We bought it from a guy who put a lot of time and money into the truck but ran out of time or money or enthusiasm. It's got a freshly built 383 backed up by a rebuilt TH400. The rebuild was done by a reputable local shop and it's got good parts in it. But my dad and I are LS guys now and we have the powertrain listed for sale in a couple places but haven't gotten much interest. What we're weighing is sale price of the 383/TH400 vs the cost of the LS powertrain and all the parts that it requires.

So what is the payoff for a completed restoration with an LS vs SBC? I say payoff because the 383/TH400 currently in it runs great, but it's by no means a race engine and we feel that the driveability and power delivery of the LS plays a factor in sale price.
