What will my truck be worth?

[VA72C10]

I have found a 67 project i want to buy and that will mean i need to sell my 1970. I have started tearing it down for body work and paint. It is a 1970 longbed fleetside with a strong 350 with Edelbrock carb and intake, headers, new exhaust with about 5k miles on it, a professionally rebuilt 350 tranny with shift kit and 2800 stall, 373 open rear, soon to be B&M floorshifter, new fenders, cowl hood, inner fenders, rad support, front and rear chrome bumpers, billet grille, chrome grille surround, all new weatherstripping, base/clear coat by professional bodyman but done at his home shop (To be completed-but his work on the cab and the finish on the fenders and hood is excellent) New inner and outer rockers and cab corners, new interior sunvisors, carpet, seats, old bed in great shape with spray in bedliner (to be done). Added power brakes and power steering. Relocated blazer tank in rear. Relocated battery to frame in drop down box. Frame was cleaned up and painted by PO. Drum brakes recently rebuilt. Cut springs (will change out if you guys think that will significantly increase the value).

Any idea of what the truck would go for completed? Here is the link to the build thread i actually just started

Here is a picture of the truck and engine and a picture of how it will look when done (minus the rims-Has 15" Rally's with beauty rings 8" front 10" rear which are painted black but i might paint blue to match the truck.- and minus the tonneau cover on the bed)
