Bought it??...sounds like ya STOLE it to me,for 800 !!
Any 4x4 diesel is well worth a grand around here without too much trouble,unless it has lots of rot or other major woes..I'd say you did pretty well for 800,I see 6.2 motors sell for 500 bucks and up from the boneyards here,and they usually are pretty beat,and need glowplugs and other work!..
If yours is a 4 spd,it MIGHT not be an SM465 in it!..I've saw,and foolisly didn't buy,an 82 K10 with a rebuilt 6.2 and a 4 speed OVERDRIVE with a NP 208 or 241 in it,for 400 bucks,in a local junkyard..they CRUSHED it without pulling ANY parts,and the truck was very salvageable,before I could get there with the cash

...the tranny was very similar to the ones mopar used in the vans and pickups,and Volare's..an "A833" New Process I believe....an overdrive is very desireable on a diesel,especially rare on 4x4's..
My 82 K20 is a stepside 8' bed,TH400 with a NP208 and a 6.2..

..best 4x4 I've had yet,and I've had at least 10 GM 4x4 trucks over the years..and I got it REAL cheap too..wont say how cheap though,in case I want to sell it someday..
