1986 Chevy C10 SWB Step Side

Recently purchased a 1986, Chevy C10 Deluxe, short wheel base step side with 108K miles. It has been is storage for many many years. It is original red/red with single stage paint????, all original body panels, cab corners have rust, however, rest of truck is good except for a few spots where paint is gone. It is a Canadian built truck, so will get factory info on it. The overall truck is very original, only change is an aftermarket radio and speakers were installed. It may still have original shocks, they look like it.

Engine started and have driven truck in drive way so far. It was trailered home. The engine has a miss, runs kind of rough. Engine miss issues unknow/undiagnoised at this time?? stuck ring, intake valve seals dried out, rust exhaust valves, bad plug wire, new plugs did help some, etc. Replaced the hydraulic clutch cylinders and line as they were leaking. It has the 4.3 V6 and 4 speed over drive transmission. Options to be posted later.

Restoration planning is on going, changes day to day, truck will be a driver to truck/car shows, Sunday drives, trips to hardware store, etc. Will do most of the work myself, restoration shops to costly. Big items- will get body work and paint mostly likely by me;
- V6 engine fix or replace with stock looking v8 (leaning toward original looking
V8) definitely O2s for tuning;
- keep trans, R and R as needed;
- frame unsure clean and paint self or power coat;
- suspension rebuild self w/some minor improvements, brakes still deciding;
- interior probably stock;
- wheels rally and street tires.

Re: 1986 Chevy C10 SWB Step Side

My next step is to register and drive some after changing fluids; engine oil, trans and differential fluids. Brake fluid will also be changed before driving. Look at brake lines for corrosion, and drive slowly.

Thanks for the encouragement.

Re: 1986 Chevy C10 SWB Step Side

Got truck registered today and took for a short drive. The engine seems to be running a little smoother. Did not get out of 2nd gear in the city. Ran pretty good most of the time, a little bucking once in a while. First impression is that, 3.08 rear gear is very low, therefor, can not go slow wo/slipping clutch. Still little experience with this combination, planning more driving soon. Preliminary thinking is to change rear gear ratio, still to be determined, including tire diameter. Next step is to fix right side exhaust manifold leak by replacing it. Then evaluate drive train components for looseness.

Re: 1986 Chevy C10 SWB Step Side

More work on evaluating engine today, changed the HEI cap and rotor, along with spark plug wires. The old cap and rotor was burned pretty bad. Wires where from 4K to 24K ohms. Pics of the HEI cap removed below. The coil housing looked like it had the factory inspection mark- a yellow dab of paint.

The drive following the above changes was much better today, engine ran much better/smoother, I feel more confident in driving it further away from our house now.

Starts very easily, has some lifter noise at start-up, however, goes away after warming up. Still has exhaust leak, more evident when driving. Looks like new exhaust system soon.

Next project is cleaning/painting rally wheels, current thinking is to go with 275x60x15s on 8 inch wheels and about 4.5+ inch BS.

Re: 1986 Chevy C10 SWB Step Side

Today worked on the rally wheels, cleaning the back sides and painted. Used gloss paint instead satin, gloss easier to keep clean.

Re: 1986 Chevy C10 SWB Step Side

Longest drive yet today, about 15 miles. I have a good assessment of the trucks condition now. Will put it away for winter this upcoming week, knowing what it needs. Was very happy with the trucks performance, with the planned rear gear change to 3.73, it will definitely be fun to drive. The four speed overdrive trans is shifting much better after being driven some.

Other note from review of truck by my master chevy mechanic today. The original u-joints are much stronger then the replacements. He said do not change them unless needed- broken. Drive line got a good review, no issues.

The truck will go in the garage next to the Buick.

Re: 1986 Chevy C10 SWB Step Side

Jeff,

Not yet hopefully soon, waiting for new paint to dry. After the above wheel pics, I ordered some argent silver rally wheel spray can paint to touch up edge where tire mounts, sprayed silver last night. Tires hopefully next week. They will be 275x60x15s per suggestions from members. Will try to post pic of fronts soon.

Re: 1986 Chevy C10 SWB Step Side

Today worked on removing pass side exhaust manifold, got 5 of 6 bolts out easy, however, the 6th one is still mostly in the head. Have got it out maybe two turns over the whole day. It will turn a little bit then tighten up. I stop, rotate it in and out a few times let it set for a while, with corrosion X sprayed between flange and head. After a while it will turn maybe a 1/16 to 1/32 of a turn more before tighten up again. Not sure what it is doing maybe galling?? Taking it slow to not break the bolt.

Re: 1986 Chevy C10 SWB Step Side

Getting back to work on the project:
O plan is to clean fire wall and reprint ( method to be determine); and
O remove inner finders and core support to clean paint.

Last weekend did a little shopping at local salvage yard, picked up several items including clock, and front sway bar.

Re: 1986 Chevy C10 SWB Step Side

Getting ready to remove bed tomorrow, first need to get some drills at local tool store ( 1/2 and 3/8 ). Plan to drill out heads. Tried to remove, bolts turn.
Also, the bumper braces at the frame are really stuck, soaked for weeks, bigger breaker bar tomorrow.

Re: 1986 Chevy C10 SWB Step Side

Removing the bed. I tried the 8 bolts and they all turned. Removed one by drilling the head with 1/2 drill ( it should have been a little bigger). Then 1/4 ed the head with a die grinder and cut off wheel. Next the head was removed with a chisel in 1/4s, just light tap removed each quarter of the head. Then the bolt was driven out through the bottom. It took a lot to drive it out the bottom several blows. Picture of tools used is shown below. For the next one will get a larger diameter drill, so that I will do less quartering with die grinder and cut off wheel. The drilling went very easy with a high quality drill( higher cutting angle so that it cuts easier). Pictures of the parts that make up the assembly also included.

Re: 1986 Chevy C10 SWB Step Side

The above picture shows the bolt, two quarters of the bolt head ( the other two quarters of the head are on the ground somewhere), the washer that is under the bolt head with a square hole, below the washer is a round cylinder that rests between the washer and the frame cross piece.

Larger picture of frame area, all the wet looking area is the drilling oil, used lots of it to protect drill.

Re: 1986 Chevy C10 SWB Step Side

Not sure why pics are upside down, they show correct in the photo index and when I launch them on the IPad. Have to check it out by taking pics at different angles of the IPad.
