Specifics on this 1971 c10 would be greatly appreciated

[Chevy_chase]

So here goes, my Step Father recently passed away. He was a Purple Heart Vietnam Vet and for some reason I dont know exactly he would get almost 5,000 a month from the government. He died die from the agent orange exposure but anyways he would always start new projects that he could never finish in two lives. besides this 71 c10 I have a 68 Beatle he was converting into a baja bug. Back to the truck, I had a mechanic over for a day and we started it up and it was the greatest sounding engine I have ever heard in my life. Tough as ****! We have everything to finish it besides the radiator which was stolen. To my questions. I am not a full on mechanic, I mean I do all my own car upkeep but when looking at this truck it is all custom. I'd like to know the engine type, whst to refer to it as and an estimated value on just the engine and also the truck complete with engine, new tires, toolbox, new exhaust system, etc. Thanks for your time
