hey, welcome Austin! looks to me like ya got a deal there - nothing wrong w/ that dry country 'sunburn', just less paint to get off
don't know if you'll have much luck finding out 'how many' anything on 60's trucks, but by then V8s were gettin more popular, and the story is that by 66 over a third of all Chev trucks produced were V8 - guess that's why they call 60-66 'the V8 era' trucks - in 65 Chev called'em "Work Power" trucks, and according to my references there was 131,395 C10s [C1400] produced in the US in 65
65 was the beginning of the 'camper specials', which option included the 283, so you may have onea those - the AC option would have also included a higher output alternator - mighta been the reason for the 'power pack' option too, tho' all the 283's then were called 'hi-torque' [327's too I think]
good luck w/ it, and thanks for the pic
Bill
