1985 C20 C6P

My latest......Picked this up the other day for a steal, It was so clean I couldn't pass it up, its a C20 with the C6P  Heavy duty Chassis package and is a Silverado Package. 350 th400 interestingly enough this can hold a bigger camper than the dually  but just 100 lbs less weight . I went and looked at it and it wouldn't hardly run, y pipe is broken and held together with a tin can and a worm clamp , I managed to drive it home 25 miles  at 65-70 mph got it home and tinkered with it to find out its got a big vac leak under the carb adapter , the dist was super loose, it is in sad shape. The ad said it had a rebuilt engine with 1000 miles ,, needless to say when i asked the guy about it he couldn't seem to locate the paperwork ..lol I  could see by the 2 inches thick of grease on the block it wasn't rebuilt but did seem to run OK on the highway.

Little cleaning up..



OK got the exhaust redone today , The Original was broken right after the Y on the Y pipe, They had it wrapped up with muffler putty and tin flashing and worm clamps..lol

I just had em replace it from there back with a flowmaster knockoff Xcelerator Muffler Hate flowmaster , but this was kinda heavy duty and its not a racecar after all.

I found a used bolt on tip out in the scrap pile.. so I asked what he wanted for it and He gave it to me for free.

Also pushed out some of the damaged rear lower quarter.


Also I knew it leaked from the exhaust manifolds, and turned out the block is a 300 hp 350 from a 70 impala with a set of 73 993 heads, old style understyle manifolds they tried to bolt up to the 85 y pipe . They had packed the flanges with muffler putty to try and stop the leaking, but it didn't work, still sounds like  at idle but the main system is now OK , debating headers or just get the correct manifolds.

Took the seat and carpet out yesterday, it was so nasty I couldn't stand riding in it until I get it redone..





Gotta love texas trucks..

Heater core had been leaking for sometime I guess,


just sprayed down the carpet to get most of the funk out till I can clean the floor off and coat it and add some dynomat and install new padding and carpet and different seats.
I go to school full time so I need to drive it 4 days a week.


dang sure smells better .

Nice find! Looks like it's pretty solid. Hopefully the floor is just surface rust.

I like it! Very similar to mine. Carpet looks better with a good cleaning. I did the same to mine the first week I got it. Exhaust system looks better. I'd just get the correct manifolds, that's the easiest way to go. It's nice to see the original paperwork and stickers.
