Title: 1986 Chevy c20
Post by: Trimmy on December 18, 2012, 01:06:54 pm
Well I recently traded a gun I had $500 in for a 1986 Chevy c20 with 155k miles on it. The truck has a 454/th400 in it with 3.73 gears. The truck has the typical rust for my area which includes the cab corners, rockers, bed sides and that is about it for me. This is going to be a slow build as I just bought a house and the holidays are making things tight for me but Im ready to get the body straightened out and rust free. The overall goal for the truck is a comfy daily driver that looks good runs good and is powered by a ppump or possibly a vp cummins transplant in front of a 47rh or nv4500  Here are some pictures of what Im starting with and any ideas are appreciated.

The first update is this, I just scored this on sale and after a military discount only paid $404 for it. Now I have to buy a 100amp fuse box and my a few other things to have it hooked up in my garage.

Well I got a deal on a 350 for my truck. I found a 1990 chevy on craigslist the guy was parting out and  called him it has a TBI350 with a 700r4 trans. He is selling me the complete motor with all accessories, harness, computer, and the transmission thats bolted to it for 500. I went and test drove the truck today and it started up, idled and ran through the gears fine. it needs new manifolds, and some cleaning but I can put it in the garage and clean on it for the next week or so until Im ready to the 454 and put this in.

Well I picked up a 1990 TBI 350 with a700r4 tranny today. I paid $550 for the motor, with all the accessories, the TBI wiring harness, computer, flowtech long tube headers, a full length 1 piece drive shaft and the 700r4 cross member so hopefully I can make that work and the transmission. It all came out of a truck I personally drove and this it was a heck of a deal. I also got an original rust free drivers door for $80 bucks..

     Nice score, now you just gotta get them in.

I know I'm going to spend a day or so going through the harness getting rid of all the stuff I do not need from the old truck. Im going to clean up the motor, pull the transmission and replace the rear main seal, and every other gasket I can get to easily... Change the fluids in the trans and the motor...

You are going to need about everything in that donor harness, short of the starter, alternator and AC wiring which should be in the 86 already.  There will be a few wires running from the box that will need to be used, should be four...

I spent three hours prepping my headers for paint today and they turned out pretty nice...

Yea I pulled everything in the truck so there are wires that ran to the blower motor, a/c, and a bunch of other stuff that definently do not go to the TBI setup. I have to find a wiring diagram to see what wires stay, and what wires go. The guy I bought the motor and trans off of said he did the same swap into his TJ and said there are only like four wires that you have to worry about, he said a few get a 12v and one or two get grounded everything else plugs in.



I also got around to buying a few parts today. I bought a bosch 13077 HEATED O2 sensor, weld in O2 bungfor my headers, Airtex E8094 (cost me $38 after gift cards and stuff I had), and 30 ft of an assortment of new wire loom to replace the junk on my current wiring harness

This is the required components to make a TBI work:
ECM with Prom
Wiring Harness
87up Distributor
Throttle Body Injector unit with correct injectors
Intake manifold for TBI, (makes for easier installation)
Coolant Sensor
ESC Module
MAP sensor
EGR Solenoid and EGR Valve (emission legal)
Oxygen sensor (Threads into exhaust pipe or manifold)
Knock Sensor)
Air Cleaner
high pressure (18-20 PSI) fuel pump (stock for a 87 will drop in any pre 87 tank)  I recommend intank pumps.
ALDL connector
check engine light (any 12V bulb from electrical store)
fuel pump relay, battery power, and fuel pump fuse in the engine compartment.
12V wire to the starter hot only when cranking
Ground wire to the back of the motor
A 16 gauge (20 amp fused) wire directly from the battery positive terminal or the junction block on the firewall
16 gauge (15 amp fused) wire from the harness to electric fuel pump
16 gauge wire from your ignition switch to the ECM (needs to be at least 5amp fused)
If you have a junction block this makes things cleaner, but you can run it in the fuse block also.

Well I got some more done today. I started on the wiring harness its almost done now. I stopped working on it after i ran out of time which was about 3-3.5hrs into it. I have pretty much the entire harness figured, I also needed to clarify a few things on it. Here eare some pics of what I have now.

Well life has struck!!! This already slow build just got slower!!! My fiance and I just bought a house and have been in it for about 4 months now. I bought a nice 60 gallon compressor and didnt have a 220v hookup in my garage and a small 60 amp service from when the house was built in 67 so I bought everything to have a 100amp service put in.  My dads buddy is an electrician so I had him change everything out and we had a lot of stuff that was doubled and trippled up in our panel from the previous owners (house was a repo) so we ran into more of an expense then was thought there. Later that night my water heater tank decided to crack so I had to buy a new water heater!!! Luckily my fiance father is vice president of a construction company and my father is a foreman in construction so we had the knowledge and know how to do the work ourselves. Then I had to buy the stuff to change my timing belt in my turbo diesel jetta so I have spent  money that was unexpected...

Well I have some good news and bad news. Good news, I just picked up a set of 906 vortec heads with new valve covers for $80. They are in great shape and hopefully will be a cheap rebuild with a little work on the exhaust side. I plan on running summits SUM-k1102 cam in this truck. Will I need new valve springs or will the stock vortec spring work? specs are

Duration at 050 inch Lift:204 int./214 exh.
Advertised Duration:278 int./288 exh
Valve Lift with Factory Rocker Arm Ratio:0.421 int./0.444 exh
Lobe Separation (degrees):112

Bad news I tore into my block and the end play was way out, so bad the crank got into the block a very very small amount so I beleive I will need a new crank.

Well more good news. I just sold the 454 and th400 in my truck. I have to pull it all tomorrow and Monday and the guy will be here to pick up Monday. That gives me the money to get my machine work done. I also found a nice 350 010 short block that was bored 30 over, has forged pistons, crank was cleaned up and has everything but heads. I might go look at that tomorrow and see if I can pick that up for less then the $700 he wants.

Post by: Trimmy on January 21, 2013, 03:31:47 pm
Well its all finally happening. The 454 is out of the Truck and Ill be getting the rest of the money for it tonight. Ill be dropping my block, crank and pistons/rods off at the machine shop tomorrow and hopefully be able to get the heads there the first of the month.

This is what she looks like now. I have some cleaning and painting to do. I have some wires I need to get rid of and need to figure out where I'm running my the TBI harness through the firewall and where some of the stuff will be mounted inside the engine bay.

Im still on the fence about keeping the a/c or getting rid of it. It would be really nice to have it in the summer time but at the same time this wont be a truck I drive everyday and if I get rid of the a/c it will look a lot better under the hood.

Well I pulled the front clip off of my truck today. I have a lot of cleaning and a few small spots of rust to cut out and burn back in on the inner fenders. I am planning on keeping this as cheap as possible so everything I can reuse, rebuild or repair will be reused, rebuilt or repaired. I do not plan on this truck being a show piece I just want something that is nice looking and nice to drive. All of the factory paint is still on the frame rails and no rust has formed so the plan is to go to Tractor supply and buy some black implement paint then clean and paint the frame rails. Here are some pictures of the progress as of today.

Great start Trimmy. Truck looks like it is solid where it counts.
Must be a great feeling for you to have a new house with a garage and a project in it too.

Starting to get the front end back into the truck after being cleaned up and primed

(http://i48.photobucket.com/albums/f242/05wranglerX/photo52_zpsb6ce7b17.jpg)

Here are the pics of the cab corner and new rockers. The gap at the bottom is not perfect but I as soon as I get the lower half of the passenger door repaired it will be perfect.

(http://i48.photobucket.com/albums/f242/05wranglerX/photo55_zpsdab5845c.jpg)

While I had the bed off to get to the cab corner I scrapped and wire brushed the rear part of the frame which from the cab back was rusty but from the cab forward it was ziebart rust protected so it is almost new looking. I got is all in a rust stopping primer then had to sit the bed back on it. I hope to be able to get it all painted black soon. I did pull the passenger fuel tank as I found a 25 gallon fuel tank from an 86 blazer for 29.95 with a warranty  that is a little over an hour away.
