Truck not starting

[dtkarst]

Ive got a 64 C20 that I take on parts runs and what not and its got a crate 350 in it that runs great. But the other day I went and parked it for the night and came back the next day to start it and drive it and it just cranked and cranked so I checked for fire and nothing. then shortly after it started to do absolutely nothing when I turn the key. It has an HEI distributor in it, I replaced the module in it thinking maybe thats what it was. PO said when it would rain that it wouldnt start sometimes but its been dry. i tried a new ignition, checked my wires to the distributor, to my starter etc. Nothing adds up. I turn the key and nothing happens. So im thinking maybe a new Distributor? Idk..Ive given myself headaches over this lol so any help owuld be appreciated.
