new truck strange motor?

[1963chevyc20]

Thank you all!! This is slot to take in. I will go a motor swap and put in a 305 v8. I will also install saddle tanks. Propane? Realley??? Wow. As for the front tires I dont know. I think it had an axle swap on the rear but I have always wanted a 1 ton. When money isn't so tight I will install some keys. The truck has an Oklahoma state inspection sticker that says 1973. I will put a pick of it up. As for the hood I will just do away with all of it and get some hindges and hood from salvage.
