Ok so I just bought this truck from a guy off of craigslist for $2k + $225 to tow home 50 miles due to no insurance. From what the seller has brought to my attention. On the forsale sign it is a 4x4 1986 GMC sierra with a "new" 380 chevy motor with 200 miles on it while I was told it was a rebuilt engine with 200 miles on it. It has 041 heads, 495 camed lifter kit, edelbrock 600 carb, street dominator intake and a new timing kit double roller. Originally the truck was a diesel but was swapped with the 380. The Body is in excellent shape minus a few small blemishes. I don't have a long enough stretch of road to drive it fast enough to see if overdrive is working but transmission has atleast 136k on it. The truck drives decent and sounds great but, there are a few things that need fixed/adjusted. I am not entirely familiar with this style of truck but it wont take me long to find out. So far what is wrong is dash transmission gauge doesn't move with shifter knob, no ac compressor but has condenser and accumulator (probably toast), heater core not hooked up (also probably toast), loose wires hoses vacuum lines throttle cable here and there hanging around, looks like bottom gas line is kinked, water pump is highly rusted on outside and needs replaced, there is a "low coolant" light lit on the dash despite it being full at the cap, missing lenses from some of the gauges, temp gauge doesn't seem to move a whole lot from 160f, might be running a tad rich because I can smell what seems like "fresh" gas from exhaust while it is running, there are no coolant lines coming from the transmission. All these issues beside, it is smoother driving than my 4.3l 1992 s10 only much louder and slower acceleration. Atm I have a working vehicle so I can still go to work to pay for these fixes. Any ideas where I should start will be greatly appreciated. Please let me know if you want/need more pics. I was thinking of getting the engine bay degreased and remove all unused wires/hoses then setting up AC and heat. I am also considering converting it to TBI even though this carb setup looks real nice.
