Awesome! Love it!

Re: 67 GMC super custom build
 

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.

Re: 67 GMC super custom build
 

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.

Re: 67 GMC super custom build
 

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.

Re: 67 GMC super custom build
 

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

Re: 67 GMC super custom build
 

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!

Re: 67 GMC super custom build
 

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.

Re: 67 GMC super custom build
 

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

Re: 67 GMC super custom build
 

Looks great!

Re: 67 GMC super custom build
 

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.

Re: 67 GMC super custom build
 

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.

Re: 67 GMC super custom build
 

Are you thinking of something like this?

Re: 67 GMC super custom build
 

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

Re: 67 GMC super custom build
 

It's home!

Re: 67 GMC super custom build
 

I see Orange. My favorite color for an engine.

Re: 67 GMC super custom build
 

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!

Re: 67 GMC super custom build
 

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.

Re: 67 GMC super custom build
 

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

Re: 67 GMC super custom build
 

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.

Re: 67 GMC super custom build
 

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.

Re: 67 GMC super custom build
 

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.

Re: 67 GMC super custom build
 

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

Re: 67 GMC super custom build
 

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

Re: 67 GMC super custom build
 

Good to know - thanks

Re: 67 GMC super custom build
 

Here's some motivation I needed. I'm using por15 engine enamel. I hope it lasts. It sure looks good now.

Re: 67 GMC super custom build
 

Looks good. Reminds me I have to paint the rubber oil fill plug on my Blazer to match the engine.

Re: 67 GMC super custom build
 

Got my engine on the stand and Unwrapped it. The block and pan need to be painted and it's not assembled yet. Hopefully I can do the block next week.

Re: 67 GMC super custom build
 

Today's progress

Re: 67 GMC super custom build
 

Lovely.

Re: 67 GMC super custom build
 

Finally it's all orange

Re: 67 GMC super custom build
 

Got my water pump on and pressed my balancer on. With the aluminium cloyes timing cover being a bit thicker than the original it's tight for space behind the water pump. Can just put a sheet of looseleaf thru it so it isn't touching. Having trouble with the pulleys lining up though. Kind of frustrating. I may try pressing the pulley base plate further down the shaft on the waster pump. It is a 5 5/8" pump. I have the balancer in the exact same spot as my original 327 engine.

Re: 67 GMC super custom build
 

I pushed the water pump pulley plate back 3/16" and it sits perfect without rubbing on the pump but barely and everything lines up now! And a few of the air cleaner and the kick down.

Re: 67 GMC super custom build
 

Got the water pump I'm using all painted up. I try to use all gm original casting parts but my original water pump would not clear the cloys timing cover without a 1/8" spacer which would put all my pulleys out of alignment more than than the 3/8" they already were so I got an aftermarket one thay does clear without the spacers. I also added a Stainless steel cover plate to avoid the pitting the steel ones all get after lots of use.

Re: 67 GMC super custom build
 

My engine builder put a melling high volume oil pump on my engine and I don't particularly like those so I got a 10553 melling oil pump instead. My screen needed to be replaced so I ordered another one but I was shipped the wrong one. I was hoping to get this running this week. Looks like it's still a few weeks away now.

Re: 67 GMC super custom build
 

Love the detail. I thought GMC used a red color on the engine rather than Chevrolet orange. Am I incorrect?

Re: 67 GMC super custom build
 

I believe 283 was red like the inline 6's were ( at least in Canada) and 327 was orange. I had a 67 gmc with a 283 and it was red. This is the original 327 from another 67 I have and it is orange. It looks pretty original.

Re: 67 GMC super custom build
 

Fog lights are in the bumper. They are fully adjustable up-Down and left-right. Might have to make a slight modification to the outer bumper brackets.

Re: 67 GMC super custom build
 

Now that is cool! Good stuff

Re: 67 GMC super custom build
 

That is super slick.

Re: 67 GMC super custom build
 

If I may, what are the light buckets from?
