Title: My 1974 GMC 1/2 Ton
Post by: Funkatation on September 05, 2015, 09:32:57 pm

Figured I'd post some pics of the truck I recently acquired. It came from the factory with a 454 and Turbo 400.  Hoping to restore it to its former self, it had been sitting for a number of years.

Thanks!

Engine is at machine shop right now. I was surprised to see a nice valve job done on it before, had 7/16" pushrods, roller rockers, etc.

I have put together some nice parts for the build:
Scat 489 forged rotating assembly with mahle flat top Pistons
Lunati hydraulic roller cam, lifters, rockets, springs, etc

I will be swapping in a 4L80e as well, and hopefully a rebuilt rear end with a posi.

Sounds like it'll be a fast, fun, and strong machine! Those are all good components.

I was super surprised it had the original grill and not a single broken plastic anywhere on it. Gotta clean it up, but it's in good shape.

Lots to update. Been working the past few days to get everything together. Hope to have it in tomorrow. (http://images.tapatalk-cdn.com/15/10/15/1e985cc93779f3e4feab973572602169.jpg)(http://images.tapatalk-cdn.com/15/10/15/4692652f5bb9f87d05b5496608a5dac5.jpg)

More progress! Hope to have her roadworthy in a couple weeks when I have time. Decided to add a trans cooler but did t have much room to fit it anywhere else. Going to route it through the radiator first and its there for my piece of mind.

Well we got her started.  Put a flow master exhaust on. Did a test drive and tranny was shifting but I was getting speed sensor codes from the tcu. Also it seems to be running warm so going to get the radiator a once over. Also very disappointed my brand new pro billet msd distributor was bad out of the box. Have to wait to get a replacement and have an old cheapie in there now. Overheating could be timing too.(http://images.tapatalk-cdn.com/15/11/15/a7383139f8bfc2d7a4d2dd498eaec0d6.jpg)(http://images.tapatalk-cdn.com/15/11/15/8c9149563c44ab01aac58f0d421b6cba.jpg)(http://images.tapatalk-cdn.com/15/11/15/ee02bf00375889fbfec8f05e45e172aa.jpg)

Very nice build and great progress.

It looks like the firewall and dash are a 'Green-Gold metallic'?  Are you going back to that? 

I see the SPID sheet is still on the inner fender, which is a good thing to have.  It might be a good time to protect it or move it.

It was originally Lime Green / White.  Not quite sure what color I'm going to go with. It has a 78 bed on it, but its not in the best shape.  Would like to get a 73-77 bed thats in good shape though.

Well it’s been forever since I updated. Shortly after I got it running I brought it home. I had lots of issues with my fitech command center, so I went with an in tank pump. Then my oil pan was leaking and my lifters sounded like a sewing machine.  I drove it back to my buddies shop and pulled the motor and trans back out. My trans was leaking all over (fresh rebuild too). That was back in July of 2016. I then found a paint guy where it sat until September of 2017. This is what it looked like when I dropped it off.

So for the engine, we pulled the lifters and cam and sent them back to Lunati. The cam was bent, so they gave me a refund.  I called up Isky and they guaranteed their lifters were much quieter. Ordered their solid roller bearing hydraulic roller lifters and a billet hydraulic cam. I also decided that since we had the motor out was to go big and get a new set of heads!(https://uploads.tapatalk-cdn.com/20180111/cb3ff7b925f8e62477d3c10398739a61.jpg)(https://uploads.tapatalk-cdn.com/20180111/aa950e814a693e3c266317d4a38c7b44.jpg) (https://uploads.tapatalk-cdn.com/20180111/28cae463c53c855cbb9a2ebe204c67fe.jpg)

During this time, I’m waiting for the paint guy to get started and got busy with work so let things sit for about a year.  I then start thinking about suspension parts and since the truck is in pieces now would be the time to do it. I made lots of calls and decided to go porterbuilt level 1 up front, stage 2 in the rear so I didn’t have to raise my bed floor.  It took about 11 weeks to get it in and started to tear into it. I also picked up these seats from someone for 300 bucks and had my dash pad recovered.

Those seats look super comfy! Do you know what they’re out of? Gonna have one heck of a ride when it’s done.

I think they are aftermarket.

So I have been spending the last month putting the suspension and motor in. Here’s a few pics.

I also had purchased a billet specialties serpentine kit and wasn’t happy with the maintenance the polished aluminum is, so ended up using cerakote on them. Think it came out good.

Then I decided to do my mirrors and door handles.

It matches the wheels perfectly.
