1968 Valiant Help

Hello all, I'm looking at a guy selling his 1968 plymouth valiant and i'm hoping to get some insight on value as well as if the project is even worth it. Any thoughts or comments are appreciated. I was told it has a built up transmission and has reverse manual valve bodies. The motor in the car is a 440 from what i've been told is out of a motorhome. The car does not drive as the owner has subframe connectors that have yet to be installed and cut fuel and brake lines in prep. He did start up the motor for me, but the headers have to finish being welded, gauges have to be wired in. Also, the body has been cut to accommodate 31.5x13.5 new hoosiers on new BelaK 15x10 rear wheels, in the front there is also new belaK 15x3.5 with newer front runner tires too. I've also been told the car has 4.56 sure grip gears which I feel are too tall for a 440, but the bigger tires might make up for it, any comments on gearing is appreciated. Another thing about the car is the front end has been completely rebuilt. The big thing with the car is parts that he has with it.

The extra parts the guy has included (not installed):
Hughes whiplash cam
comp cam "pro mag rocker kit" part number 1621 - 16
Winters side winder shifter
Full MSD ignition system with 6AL-2 box
complete Single plate nitrous system NOS brand - has jets, plate, controller and bottle
Holley 750 double pumper.
The guy also has another bare block outside of the car that has been sonic tested and passed (has report) and the number it is: 7 - 11 - 67 /; 2536430 - 9

The number on the block is:
11- 17 - 74
4006630 - 440 - 9
D - N

The number on transmission:
2C 100716

The stamping on third member is:
2881469

The guy wants 10k for the car and everything, let me know what car is worth or if it is a project worth finishing. Like I said above, any thoughts or comments are appreciated. I have seen car in person and might be able to answer questions you have about it.
