Re: Project Screamer - '72 GMC K2500 + DD 4-53T
If I could find a good deal on an inline 6-71, I'd be doing one. :lol: I did an 8v-92 in a military truck chassis with a 86 crew cab drw body years ago. I should have kept it. The engine was 550hp silver series with a 10 speed. It rocked!

I have seen a number of DD engines offered at good prices. I would have liked to have seen your truck. It sounds awesome. |
Re: Project Screamer - '72 GMC K2500 + DD 4-53T
It may still be around. I sold it to a guy in Nebraska. The Lincoln area I think. I saw a video of him pulling it at the Wahoo truck pull years ago, but can't find the vid now.

A few more rainy afternoons and a little more progress...
I have had some time to work on the exhaust since it has rained the last couple of afternoons. Here's the section from the down pipe to the muffler on the bench: Attachment 1434823 Here's the view from the front: Attachment 1434824 Here's the view from the rear: Attachment 1434825 Here's the view from the driver's side. I knew that I would have to pop up and over the transfer case cross member. I think that it worked out pretty well. Attachment 1434826 Note the size of the muffler. It's a MagnaFlow straight through design. It should sound pretty nice... |
Re: Project Screamer - '72 GMC K2500 + DD 4-53T
Looks fantastic! The t case looks like it's swaddled in cozy blanket made of extra manly beef!

Re: Project Screamer - '72 GMC K2500 + DD 4-53T
Great work on the exhaust!

I finally spent some time on the old '72. I have been doing everything but working on it for the last couple of weeks.
I have finished the exhaust tubing. Here's the tail pipe on the bench: Attachment 1442004 Here's the top view: Attachment 1442005 Here's the rear view: Attachment 1442006 I need to purchase hangers and fabricate the supports. Then I can call this task done. |
Re: Project Screamer - '72 GMC K2500 + DD 4-53T
That is an awesome, massive pipe. 4"? Keep sending pictures, this is becoming an epic build.

Way back on post #43 you mentioned the engine stop leaver. Could you show it close up? I assume the lever shuts off the fuel flow.
I don't have a diesel in my '70, but and "Engine Shut Off" leaver just sounds cool! |

Attachment 1442793 On the 2 cycle Detroit Diesels, the engine stop allows the rack that connects to the injectors to retract fully, stopping fuel flow at the injectors. |
Re: Project Screamer - '72 GMC K2500 + DD 4-53T
Thanks. That looks cool, of course for you it would be functional as well.

I ordered a radiator, exhaust hangers and cruise control. Since the radiator arrived first, I thought I would sit it in the core support and see how it looked.
The radiator is a 2 pass unit from Speedway Motors. It is based on the Chevrolet pattern. I ended up with a 2 pass radiator because the A/C compressor blocks the path from the engine thermostat housing to the driver's side radiator outlet. I couldn't mount the compressor on the passenger side because of the location of the water pump & alternator. That's why I like to mount the engine accessories early... It is a couple of inches shorter than the OEM radiator (it is the widest one that they make). I priced a custom radiator so I could get the exact dimensions - very $$$ - more than 3X the price of this one. Here it is on the bench: Attachment 1443238 Here it is sitting in the core support. The core support has 2 positions for radiator supports and this radiator would work in the narrower position. Unfortunately, the fan would be way off center so I am thinking this is where it will end up. Here's the front view: Attachment 1443239 Here's the side view: Attachment 1443240 It is a gorgeous radiator and I like the look of aluminum; but, I really want to paint it black... |

Not much happening on the project these days. The aspen leaves are already starting to turn so my time for working outside in comfort is limited.
I did get the opportunity to weld the exhaust hangers on for the back of the truck. Here's a view of the one attached to the transfer case cross member: Attachment 1447135 Here's a couple of views of the one at the rear of the muffler. I had to build a bracket for this one: Attachment 1447136 Attachment 1447138 I am planning to attach a hanger to the transmission rear support. I haven't been able to start on the rear support because I can't get the plugs that fill the holes for the mounting studs out of the back of the transmission. I'm being patient and working on them gradually since a busted transmission case is a $1000 mistake. The radiator had to go back - it didn't have any threads in the filler neck for the overflow. I will work on mounting it when the new one arrives. For now, outside work takes priority... |
Re: Project Screamer - '72 GMC K2500 + DD 4-53T
Looking good! Too bad about the radiator. Are you going custom, or going to use something similar?

We got 4" of wet, sloppy snow today. Woo Hoo, a truck day!
I started work on mounting the new radiator in the core support. The tanks of the new radiator are about 1/2" taller than the original radiator, so I had to modify the bottom mounts so it would look "stock" at least from the top. Here is the modification for the passenger side tacked in: Attachment 1459230 Here it is welded: Attachment 1459229 I don't know how the guys on TV mount a radiator in 10 minutes. I spent all day and don't have much to show for it but a big smile... |
Re: Project Screamer - '72 GMC K2500 + DD 4-53T
Nice work. The guys on TV have the pause button on their side. Haha
|
Re: Project Screamer - '72 GMC K2500 + DD 4-53T
Creative and functional. Nice work, even though it took longer than 10 min!

Another snow day - I'm starting to be concerned - I'm looking forward to snow days...
I completed the radiator mounts. It looks good in the truck. Here's a front view: Attachment 1463895 Here's a side view: Attachment 1463896 While mounting the radiator, I noticed that there was no drain. Don't radiators always come with drains? Apparently not. I purchased some 1/4" NPT aluminum bungs from Summit Racing so that I could make my own drain. Here is the drain bung in position: Attachment 1463897 There's no turning back now! Attachment 1463898 No leaks! Attachment 1463899 Job done. Now I need to find some hoses for it. I have tried a couple from the Gates catalog. It looked like they might have worked; but, unfortunately they didn't. |
Re: Project Screamer - '72 GMC K2500 + DD 4-53T
Looks great! its always nice to get things like that checked off the list. big ticket items like cooling, fuel, exhaust... the things you have to have to make bad air.
i like the CO2/Ar bottle cover. mine usually has similar fashion sense. |
Re: Project Screamer - '72 GMC K2500 + DD 4-53T
Nice progress!
