My 1980 Silverado build thread
 

Hey guys and gals. Just wanted to start a build thread for my 1980 short bed. So here is the history.

The truck is a 1980 Short bed Silverado 2WD that I bought from my Father in-law. The truck had been stored in is shop for the past 10 years. It has 80,000 miles and was pretty much bone stock minus the .243 bullet hole in the floor. It still has the functional 8-track player :metal:.

So far I have pulled out the blown 305 and installed the motor I originally built for my 69 C10. I do need some help with the motor but ill get that in a later post.

Here is the stats so far.

What a find! Looks like a great truck. Nice job on the engine bay clean up.

Re: My 1980 Silverado build thread
 

Time for an update......

Eaton truetrac installed, 3.73:1 gears installed, Disc brake conversion done, 4" drop on the rear done, 3.5" drop on the front done. 3" x-pipe with Borla mufflers installed. Weld wheels on the front (been waiting on the rear wheels since June.... Weld is slow) Fi Tech 600hp Power adder is going on this weekend. So hopefully she will be screaming down the road soon....

Re: My 1980 Silverado build thread
 

That thing's gonna be squirrelly. Nice truck!

Re: My 1980 Silverado build thread
 

Its all over the road with the factory tires on the back. I have M/T tires for the back but no wheels to put them on. I've been waiting since June for Weld to build them for me.

Re: My 1980 Silverado build thread
 

VERY NICE!!!! I've always loved the 1980 :metal:

What rear disc brake kit did you use? Parking brake or no? Do you know what the rotors are from, for replacement?

That 383 is going to be awesome! :chevy:

Re: My 1980 Silverado build thread
 

Caliper brackets are from Speedway, Calipers are D52 from a 1980 c10, Rotors are 1999 AWD Astro rotors, break lines are front lines from a 1980 c10 as well.

Re: My 1980 Silverado build thread
 

Looking good, did you get your Weld wheels in the rear?

Re: My 1980 Silverado build thread
 

Any updates?

Re: My 1980 Silverado build thread
 

Well I guess I should do an update on the truck. I have been spending most of my time over on the turbo forum trying to get all the bugs worked out and the truck is pretty much done now.

So I blew the 383 to pieces one day. (long story about FiTech that I wont go into)

Found me a 6.0 LQ4 out of a 2006 Yukon Denali. Yanked out the old 383 and started getting the motor ready for paint.

Re: My 1980 Silverado build thread
 

Fast forward a few months and I installed a LJMS stage 2 turbo cam package with push rods and valve spring, Got some up and forward turbo headers and built my hot side and exhaust.

Edit: Sorry for the sideways pictures. Just pick your monitor up and turn it sideways for the full effect.

I will fix the sideways pictures tonight on my laptop. My work computer wont let me turn them to the correct orientation.

Re: My 1980 Silverado build thread
 

Next up was the cold side.

Re: My 1980 Silverado build thread
 

Next was a holley High Ram, Deka 80lb injectors, Dual 400lph pumps, Holley HP EFI system, 4" down pipe, fender exit exhaust, and other odds and ends.

Re: My 1980 Silverado build thread
 

Nice ride, I will follow along.

Re: My 1980 Silverado build thread
 

Over the past few weeks everything has really started to come together. I have the truck tuned and driving awesome. I relocated the coils and have started cleaning up the engine bay. I have the truck entered at the C10 Nationals at Texas motor speedway in may so its been a mad dash to clean it all up.


This has all been a learning experience for me and I have had a ton of help from other forums and friends.

If anyone has any questions or wants other pictures let me know and I will post them.

Thanks for following along.

dayummmm

Re: My 1980 Silverado build thread
 

Looks good man. Why Holley EFI vs GM PCM and HPT?

Re: My 1980 Silverado build thread
 

I really liked the user interface of the Holley and the built in digital dash. I have a Megasquirt system on my wife's car and tuner studio was ok.

Ive never messed with HP tuners but I do know they offer a very nice system but I guess the main reason I went with holley was the harness. I think they had the nicest quality harness. Plus all of the built in ICF's are a huge time saver.

Re: My 1980 Silverado build thread
 

Amazing.

Re: My 1980 Silverado build thread
 

Talk about a full house. That engine compartment is full. Looks nice.

Re: My 1980 Silverado build thread

Re: My 1980 Silverado build thread
 

Wow That is a Mint V22 Option 1980 truck! There are LESS & Less around.
