67 GMC super custom build

Yeah she is full of extra weight that's for sure. Here is the passenger side.

Awesome! Love it!

I got a set of Nos left and right dual exhaust mufflers parts 3861811 and 3861812. They have 2.5" inlets and 2.0" outlets. I think everything gm put out had 2.0" outlets in these years. They are correct for 64 327 with high performance (not special high performance). The engine I'm using is a 64 327 300hp so I may use them. My original truck motor will stay on the stand. Not too much original about this truck any more anyways.

[chewychevy67]

The 300hp used an afb carb from factory and I wanted to keep it looking stock with a 4jet. Now since my original 4jet was small and was really for the original 220hp engine I had a new 4gc custom built for my new built 327 specs and added the turbo 400 kick down throttle arm to this carb. It has the base of the 409 340hp carb to match the 300hp 327 intake design. It's not as stout as the 409 carb though. It will be more suited for a small Cid engine. I'm going to send it out to get the body recolored soon. I may use the original 2.5" exhaust manifolds that were on the 300hp engine and not put the smog pieces on the engine.

The gm page shows what the mufflers are correct for. I wonder how quiet and restrictive these will be. There heavy. Wish they sound like a turbo muffler.

So many interesting details on your build! Fantastic work. Sub'd...

Great build you’re doing! I just finished reading all of it over the past couple days.

You will really like the Twilight Sentinel, it is one of my favorite things about my Cadillac. The caddy has an additional post-shut off functionality, if you leave a turn signal on, it turns on that side’s cornering light also. Not sure how you can use that, but you’re pretty creative.

The Guide-matic is cool too, but the road signs are very reflective now vs the 60s. The lights tend to dim when the signs reflect back at you. Otherwise, it is a very slick system and works great as designed.

I never thought to join a switch pitch 400 and a Gear Vendors, what a great combination. I’ll take that over a 700R4 any day.

Keep after it!

[chewychevy67]

That's interesting how the signs have changed. I never thought of that. Totally makes sense. I have thought about cornering lights as my turn signal switch has the wiring. I would like to somehow put a lens in the front of the 67 68 body mouldings so it doesn't disturb the body lines but not sure if I'll get that crazy.

[chewychevy67]

All machined and ready for some guts. Heads are done already too!

[67_C-30]

Looks great!

[chewychevy67]

I bought a transmission oil cooler for the truck. With the variable pitch converter I wanted to make sure it won't get too hot. It's made for 1971 mopar cars. I like that it has thread fittings instead of hose and clamps. Going to mount it in front of the air conditioning condenser.

[chewychevy67]

Found me an original front bumper so my bumper guards would fit properly. The aftermarket one looks ok but left big gaps with bumper guards. I can get my fog lights in here nicer cause it's painted.

[67 Burb]

Are you thinking of something like this?

[chewychevy67]

I bought a few different timing tabs for my aluminium timing cover and none of them were correct according to my original timing cover so I used the tab welded to to the original cover and made one. I used a Nos balancer that is exact to my original so this should be correct. I know they moved the marks in the later 70s on the balancers and timing covers so this could be the reason why I couldn't find a correct one. The later balancers timing mark doesn't line up wuth the key way like the earlier v8's.

[chewychevy67]

Started figuring out the transmission cooler mounting. Hope it doesn't take too much away from my air conditioning. The rad is a 4 row so it should be good.

[chewychevy67]

Yes. Im going to mount the bumper guards on the frame horns and mount the fog lights really close to where you have them.

[chewychevy67]

It's home!

[Getter-Done]

I see Orange. My favorite color for an engine.

[chewychevy67]

Got my new carb back from being recolored at Chicago carburetor. It looks great. This is the second one I've had them do and they do good work. Just in time to get this engine running!

[IronCanine]

Late to this party for sure...though I've been following for a little while. Carb looks great. Love the creativity and craftsmanship and the unbelievable parts. Impressive work. Thanks for sharing.

[Getter-Done]

That what carburetor's are suppose to look like.
That the way I remember them.
Money well spent.

Purchased a Nos ac condensor for my 67 from w314speed and a brand new compressor from alma products with the plug clocked at 10 like factory.

[DeadheadNM]

Did the compressor arrive that way by happenstance or did you request the plug be clocked at that location?

[chewychevy67]

I requested it. Normally I think they come at 2 o'clock.

[DeadheadNM]

Good to know - thanks
