383 value?

I recently got a 383 in a trade that I am going to put into my scamp, the person who I got it from owed me some cash. He couldn't pay so he gave me the motor out of his older dodge truck said it has recently been rebuilt and bored.

The numbers on the block where D383-1023 R.

Looking it up looks like its a 1968 383 from Oct 23.

There was a tag on the drivers side that read
.60 Bore .10 Rod .10 Bearings

I did drive the truck before we pulled the motor and the thing ran like a raped ape, would smoke the duals off the back of the truck with no hesitation what so ever. Looks like a stock intake and has a quadrajet carburetor, I'll get the casting numbers from the intake and heads when I get a chance later. Over all it looks very clean, no oil seepage anywhere and clean paint.

Does anyone have a estimate on how much this motor would be worth. I think I came out ahead on the deal.
