Re: 67 GMC super custom build
 

I just read through this whole thread. Absolutely amazing work! Boy I wish had anywhere near the patience you have....

Those valve covers are amazing. As is everything else you've done.

Great work!

Re: 67 GMC super custom build
 

Thanks. I appreciate it. My engine builder said I should be ok with that oil pump so I can soon get it in the frame. With covid19 out it may take a bit as I can't have anyone over to help so I may find a few other projects to do before the drivetrain gets in.

Re: 67 GMC super custom build
 

So far out of all my truck engine/trans/gear combos, my favorite by far was the T400/Gear venders/3:73 in my 78 SWB. Loved it!

Re: 67 GMC super custom build
 

Yeah I'm pretty excited about the driveline. I wish I would have done 3:73 or even 4:10 but I hope the 3:55 rear will be ok. My engine builder built my engine for those specs so I'll leave it now.

Re: 67 GMC super custom build
 

Got the damper side all finished up today. Tomorrow I'll start doing the easy lift side of the gate,

Re: 67 GMC super custom build
 

What did you use as a nut to hold the damper in place?

Re: 67 GMC super custom build
 

It actually a piece of 1/4" flat that I tapped and welded on the Inside of the gate. It fits perfectly with the spacing of the handle of the damper. I did File out and add a piece into the damper so when I tighten it up it gets sandwiched nice and tight.

Re: 67 GMC super custom build
 

Started the other side. Made a bushing for the rod to ride on. Now to the other side where the rod goes into. That will be a little more of a challenge to make.

Re: 67 GMC super custom build
 

That is a sweet mod.

Re: 67 GMC super custom build
 

Very cool. Where are you getting the delrin bushings?

Re: 67 GMC super custom build
 

I got them from member 1966chevy some time ago. It's unbelievable how much quieter it operates now.

Re: 67 GMC super custom build
 

This works just like crossbreed's video. I'm glad I did this mod. I have a few things to do to finish this up but for the next bit I'll be finally getting back to work for a couple of days. This is how my trunions ended up looking. Took more than a couple hours and about 200 bucks but we'll worth it.

Re: 67 GMC super custom build
 

Nice Addition.
Looks great:metal:

Re: 67 GMC super custom build
 

Got a bit further on the gate tonight. Got the bushing into the gate tight so it won't come out and started the piece that holds the rod inside the gate.

Re: 67 GMC super custom build
 

Got the piece made for the rod to stick into. Now to weld it in and see how it works.

Re: 67 GMC super custom build
 

This is such a great mod! Please post a video of it in action when you can.

Re: 67 GMC super custom build
 

Someone needs to do a step by step write up on this tailgate mod! I am loving watching it come together!

Re: 67 GMC super custom build
 

Got my new oil pump today. Same pump as before but with the shark teeth designation. Way quieter and less restriction. Looks like I'll be changing the pump in the next couple of days. Glad I cought this before I installed the engine.

Re: 67 GMC super custom build
 

Just wow, came across you build and read from start to finish, so many well done add ons and details. Great job to this point.

Re: 67 GMC super custom build
 

Thanks. Hoping I can get you guys a video of the gate in the next couple of days. Just waiting for a part in the mail. It's taking extra long to get stuff these days.

Re: 67 GMC super custom build
 

Picked up an engine run stand last night I'm going to use to break my engine in. It supposedly doesn't need a radiator. It has adapters on eack end of the rad hoses st hook up to your water tap. Has anyone ever run an engine like this? Seems like pumping constant cold water into a warm engine would not be the best.

Re: 67 GMC super custom build
 

Although I have only run an engine with the garden hose trick once, I would suggest having a valve on the outlet end of hose coming out of the thermostat housing so you could monitor the engine temp and adjust the valve accordingly.

Re: 67 GMC super custom build
 

Yeah. It might be best to moch up a radiator for it as well. Not worth ruining a brand new engine.

Re: 67 GMC super custom build
 

Right. Better safe than sorry.

Re: 67 GMC super custom build
 

New oil pumps in. The shark tooth design is quite a bit less restrictive to rotate by hand and is much quieter. I'm really glad I changed it out. I also straightened out the pan. The longer bolts that come with the gasket aren't crowned like the factory ones were and they just pulled in where the holes are. I found longer ones that are crowned that fit properly and won't damage the pan hopefully.

Re: 67 GMC super custom build
 

Here's the tailgate video! Watch "Tailgate" on YouTube
https://youtu.be/nP6ysgoDLyE

Best part of this mod is there is no way to tell its there with the gate mounted.

Re: 67 GMC super custom build
 

These old Chevy and GMC tailgates are heavy, and this mod stops the thing from slamming. Well done, now I have more work to do.:lol:

Nice work!

Re: 67 GMC super custom build
 

Got my original 4 row harrison rad back today. Had it re-cored. That was not cheap but it was worth it. Sure is heavy.

Re: 67 GMC super custom build
 

Looks great.

Re: 67 GMC super custom build
 

My gas tank neck wasn't centered for some reason and I don't think it sealed properly so I massaged it to be centered and I removed it. I'm going to have it cleaned and lined by the rad shop that rebuilt my rad. I know that it will fit properly unlike some repos I've heard of. There is still the glue on the tank that held the carpet down behind the buddies.

Re: 67 GMC super custom build
 

Tank came back today nice and clean inside and no leaks. Now I have to Get this glue off the outside and clean it up. Maby paint it? Not sure. I'll have to check around to see what ppl on the board are doing. Had a little repair done on the neck too. After I centered the neck in the cab hole it needed a little touch up at the base.

Re: 67 GMC super custom build
 

Got the glue off the tank. The original finish must have been just shiny bare metal as you can see its cleaner where the glue was removed. Possibly galvanized? Anyway I'm not sure if I'm going to paint the tank or just put it back in as seen here all cleaned up.

Re: 67 GMC super custom build
 

So the more I think about it I don't want the spillage out of the cap when I make a left turn like can happen with the vented caps so I may purchase one of these fill restrictors for the fill neck. It won't block it off completely but will stop some of the slosh from getting to the fuel cap.

Re: 67 GMC super custom build
 

Well I had to change my oil pan gasket to the thinner front seal. The site clearly states that a pan with 2 3/8" smile requires a thicker gasket but that's bs. Mine is clearly that deep. The first pic is with the thicker one. The second with the thin one. At least the gasket is reusable if I ever need one for its application.

Re: 67 GMC super custom build
 

Got the pan back on with the new gasket. Worked nicely. Also got the engine on the run stand. I'm not sure if I'm going to run it on the stand or just get it on the frame and break it in before I hook up the torque converter so the transmission doesn't connect. The stand seems a tad bit flimsy. I just hope it won't leak. The new oil pump runs 100% quieter than the old one when priming the engine! If I do run it I'll need to make a stand for the radiator

Re: 67 GMC super custom build
 

Got the engine timed and the distributor and wires on. Hopefully Sunday I can get the rad stand built and get the gauges hooked up. Then possibly a Monday or Tuesday breakin!

Re: 67 GMC super custom build
 

Looks great!

Re: 67 GMC super custom build
 

Been off for a bit...nice to come back to lots of cool updates. And this is hands down the coolest build. Here's to a smooth break-in! Looks great.

Re: 67 GMC super custom build
 

Good luck on the break-in! Looks great!
